We bought a new Sony Bravia last week to replace a 16-year old Panasonic CRT model which was playing up. We are very pleased with the Sony except the picture is not quite as good as we expected.

When using the in-built digital Freeview tuner, the picture is very good. When viewing Sky via a SCART lead the picture is pretty good. But we also have a HDD/DVD recorder connected to the other SCART output on the Sky box (not Sky +), and this feeds back to the TV to the second SCART socket, and the picture from this is barely acceptable. If viewing Sky through the DVD recorder in standby mode, the picture is fine, but when it is switched on the picture changes to 4:3 format. I can change it manually each time on the TV but this seems then to downgrade the picture - perhaps it is stretching or distorting it?

I have checked the cables are securely fitted and have swapped them around but it has not helped. I have tried various settings on the Sky box and the DVD recorder and unfortunately nothing helped, but I now think I may have discovered the reason for the poor picture - it's the HDD/DVD recorder itself. It's a LiteOn machine, and it was brilliant with my old TV, but it is an old model and I believe it is simply not compatible with the 16:9 output ratio coming from the Sky box.

LiteOn have a very good support team, I spoke to two different technicians and they both told me the same thing. Even though there is an option on the LiteOn menu for 16:9 video output, it appears that my model of machine is simply not capable of doing it. So I believe it is recording at 4:3 ratio and then when I manually select 16:9 on the TV it results in the inferior grainy/fuzzy picture quality.

I was thinking I would have to get a more modern HDD/DVD recorder but I tried my DVD recorder on my sister's TV and it works fine - but she has Virgin cable instead of Sky. It's all rather baffling.

Your thoughts will be appreciated please.

I think only one of the Sky's scart sockets outputs RGB, the other will be composite which is crap.

You should connect the Sky box to the DVD recorder using the RGB scart socket, then the DVD recorder to the TV.

I think it is the TV scart on a sky box which outputs RGB.

Ok set up should be:
Sky TV scart ---> DVDR input
DVDR output ---> TV AV1
Try and set the Sky box and DVDR for RGB
Forget any scarts from the Sky VCR scart

This is called passing the Sky signal through the DVDR. It looks like the DVDR will pass through RGB when it is in standby but not when it's turned on. This may be due to the settings i referred to above or that Liteon doesnt do it!

testing for an RGB signal is easy, Some TVs display 'RGB' when detected but another way is to set Sky to a menu and look at the corners and edges. these will be pin sharp in RGB but blurry in composite. Have a play with the 'video' settings in the Sky picture menu.

I bet the VCR socket on the sky box is only a composite output, isnt it?

Ive had my dvd recoder plugged into this for the past couple of months. I bet this is why my dvd's havent been coming out great quality.

ok, this thread has made me question my own setup.....

only ONE of the sky scarts has RGB out, SO I connected this to the DVDR input.

When I switch the DVDR on, the TV dispalys RBG in the corner, and I can tell the improvement. It looks like my TV only has 1 RGB input. the second scart socket dosent support rgb. is this normal?

Also, my DVDR dosen't seem to pass the RGB signal through. Even when it's in standby. The picture from my sky box seems to be in composite.

I dont think im explaining myself very well here :s

DVD recorders output RGB, I think my Panasonic has two, but yours should have at least one RGB output.

Make sure you have your Sky box set to RGB in the system menu, by the way.

Its only a cheap LG dvd recorder.

The picture from the dvd comes out in RGB, but when it's in standby, it doesnt pass through the sky box in RGB... it looks like composite.

(the sky box is in RBG mode - when I connect scart 1 on the sky box directly to scart 1 on the TV, it looks great)

Have you checked the advanced menus on your DVD recorder, there are usually some good ones hidden away. You might find something - there is no reason why you shouldn't be getting RGB through - it isn't a luxury item.

As good as the Bravia is I think you have found out what most people do, which is that a shiny new flat screen LCD will never be quite as good as your old CRT.

Many thanks for all your feedback and ideas folks. I have followed the recommendations frm stvn758 and Scorpio but it hasn't helped I'm afraid. It looks like my Liteon will only record in 4:3 format after all.

As a final test I am planning to take the unit to a friend's house and plug it in to his Sky system at the weekend. I'll report back in case anyone is interested.

I cant SEE anything in the dvd menu.

there are only 2 that it might be.... "AV2 Connection", you can have Decoder, or other device. Ive tried both, but they dont make much difference.

The other option is Video Output Format. RGB, or YPbPr. Ive left this on RGB.

It just looks like my DVD recorder cant pass through RGB. Which is rubbish. Unless theres something Im doing wrong?!?!

LiteOn DVD recorders in the past have been composite input only. This may be where your problem lies.

That's the norm for LG DVD recorders. I've got a DR175 and mine's the same. RGB passthru when switched on, composite only when in standby. I got round it by connecting my Sky+ box to my TV using s-video, TV scart on Sky+ box to LG (for recording in best picture quality), VCR scart on Sky+ box to VCR (for those few occasions when I wanted to record to tape).

When watching Sky, I had the choice of switching the LG DVDR on and watching in RGB via two scart leads (Sky to DVDR to TV), or watching via the s-video connection directly from Sky+ to TV (and the difference between the two was negligible; whereas the difference between RGB and composite is massive).

According to the Sony manual both it's SCARTs are RGB equipped. So why not connect both Sky and DVD direct to the TV one to each SCART?

If you want to record Sky on the DVD then use a third lead from the Sky box to the DVD.

Something like this...

Sky "TV" SCART --> TV AV1 SCART
Sky "VCR" SCART --> DVD AV2 SCART
DVD AV1 SCART --> TV AV2 SCART

Set both the Sky box TV SCART and DVD recorder AV1 SCART to RGB and that should work. Unless Sony are lying in the Specs at the end of the manual and the letters RGB alongside the little icon for the AV2 SCART mean something totally different to the letters RGB alongside the AV1 icon

But on the other hand it seems all attempts to daisy chain the Sky box and DVD have failed miserably.

And anyway by the time the recordings have been mangled by the MPEG encoder in the DVD would it really matter hugely that the source is not RGB

Personally i would rather have the main sources of viewing, live TV and movies on DVD, in the best quality and could live with the odd recording not being at it's best.

Others may have different opinions of course.

how do I connect the sky+ box to the tv using s-video?
so, s-video is somewhere in between scart RBG ,and scart composit.

what is the point of composit anyway. I just looks like shit. at the moment I can choose between viewing sky in good quality, or recording dvds in good quality.

S-video lead and two phono's from the back of the Sky+ to the TV's S-Video and audio inputs.

It's what has always been used in the past, and is of a similar quality to a VCR.

So does the s-video lead carry a RGB or a composite one? or is it something totally different?

If its of similar quality to a VCR then im guessing the quality wont even be as good as the composite scart connection i currently have?

also does the s-video carry a widescreen picture? and will it automatically switch onto the correct AV, the same way it does with scart.

sorry for bombarding uze with questions!

It carries the B/W and colour signals separately, it's bascally PAL before it's added together to make composite.

No, it's composite that's VCR quality, S-Video is similar but avoids many of the problems associated with PAL, and it's those problems that make the picture poor. S-Video is a long way short of RGB quality, but it's not far off as good as DVD or digital TV signals - try it and see, it's a LOT better than composite.

It carries a PAL picture, no widescreen switching, you would have to manually switch.

I also use the S-Video connection and carn't see any difference between that and scart, maybe my scat cable isn't that good but good enough.

If I'm honest I still use the rF connection as I carn't be be bothered to select AV all the time.

so would this be suitable?
http://www.dixons.co.uk/martprd/stor...&category_oid=

and I would have to have the white and red phono leads to carry the sound, as it is not included in the s-video lead.

Also, what is this YPbPr thing? im presuming its something to do with high def, or lcd \ plasma TVs, its not something ive seen in the past.

Yes, that's the sort of lead you require.

Yes you do, the mini S-Video lead is picture only.


Also, what is this YPbPr thing? im presuming its something to do with high def, or lcd \ plasma TVs, its not something ive seen in the past.
It's called Component, it's what the Americans used instead of RGB - but because it's American it was updated to carry Hi-Def as well, where RGB never was (because the Americans don't use it). It's very slightly inferior to RGB, as it's encoded slighty from RGB - but there's generally no RGB quality sources anyway.
