Its funny you should say that i was thinking the same this afternoon, also the "original" Vformat dont seem to change anything when you switch from 1080i
I don't know whats in your head,but I have 2 very good eyes in mine and they are seeing a drop in pq!!!!
With the high quality SD stuff the BBC have been putting out on their HD channel lately it hard to tell if its the receiver or the system.
Just finished watching around the world in 80 days and if it was not for the fact that my HDR is connect via HDMI only, I would think its connect via SCART.
Quality improved now for Jools Holland.

When I downloaded the update I straight away thought the PQ was a little worse but thought it may be me just looking to "deep" for changes. The thing that convinced me their was a change is when my normally "apathetic" techie wife commented that the picture quality seems bad at the moment!
I notice a massive difference in using the V ratio button with only 720p (my native TV res) giving anything like acceptable non soft images.

I haven't really noticed a difference - if anything I wonder if the SD channels are slightly better? I have noticed that the BBC HD is of a very variable quality and some programs are superb others very often mediocre and not much better than SD.
I think that SD is very good now on some of the main channels. BBC and even channel 4 at times - my wife likes Ugly Betty
and I thought the quality of the image, at least, was pretty good for SD.

Watching various wildlife programmes transmitted both before and after the update (not that that should make any difference) everything seems to be at the same quality as before.
I haven't had to make any chances to picture ratio adjustments.

I have noticed a difference that just happened to coincide with the Foxsat FW Update.
BBC Have reduced their BITRATE on HD Channel, to match future Freeview HD Channels. They claim it won't make any difference to PQ, but obviously with so many noticing it, it is. Read this article. - http://www.techwatch.co.uk/2009/11/1...cture-quality/

It might have the knock on effect of making SD seem better though! All this messing around with the bit rate makes it hard to spot consistent good quality.. one minute very good on HD next you think that your eyes are playing up

The bitrate change happened at the beginning of August, so it didn't coincided with the firmware update.
From what I have been told there have been no changes to picture processing other than a slight increase in overscan.
If you look at the BBCHD testcard and you have overscan turned OFF on your TV, the old firmware positioned and sized the card perfectly.
With the new firmware the bottom is still correctly aligned but the top and sides are slightly overscanned. You lose the tips of the triangles.

On my TV set to full pixel you get the full picture over hdmi set to 1080i or 720p but at 576i or p it overscans and it's the same with a SD transmission

If this is the case, why is it only now, 3 months afterwards that lots of viewers are reporting a worse PQ? The BBC have already admitted that HD on Freeview PQ will be worse than that on Freesat by saying bitrates need reducing to match that on ALL platforms. If they want everyone to have the same on ALL Platforms, why not reduce it further down to i-player levels! (Rant Over)!!

Actually when HD is launched on Freeview, it has the potential to be higher quality than satellite due to statmuxing, which is a bizarre state of affairs. See this post.

In addition to what Les just pointed to, they don't follow the same bitrate rule on Freeview/DAB/satellite for BBC radio so why on Freeview HD and Freesat HD/Sky HD for BBC HD
?

If true, that would be very strange, because it implies the whole picture is being scaled (and hence, softened).
The HDMI feed should be a 1:1 pixel mapping of the broadcast (or 1:1.3333 horizontally to unsqueeze BBC HD!). Anything else implies a loss of resolution / quality / sharpness.
(I'm only watching via RGB SCART, and I haven't noticed any change in quality. The HDR is far better quality than our very old Sky box).
Cheers,
David.

Bearing in mind how much of ITV and CH4 is actually in HD then Freeview BBC HD will be better.
Anywhere doing pre-orders for Freeview HD receivers.
Been noticing a few times since the update, Channel 4 shows some weird pixelations in a part of the picture. Only this channel, and only sections of the picture...usually when the camera shot changes....

Yes, quite !!
I wish I'd taken a shot before the s/w upgrade, here's one from this week:-

There's virtually no overscan on the picture. The tips of the triangles are the edge of the picture indeed on your TV you can see the noise at the bottom edge indicating the picture needs to come down about 1 pixel. On my Sony TV I can clearly see a 1 pixel red border drawn around a 1920 x 1080 frame grab of the BBC HD test card and displayed by my hdr. The new firmware does some funny things to SD pictures using scart though

I get exactly the same thing,and only on channel 4.
I'm a pretty old geezer and I don't really understand much about bit rates etc etc,so I just put up with it,but I do know that it wasn't like this a month ago.

On the subject of quality, the latest edition of HD Top Gear (aircraft loader racing) was absolutely pants quality. Clarkeson's face was positively blurry in the studio.
Well done BBC. Another quality programme that can look fanatstic in HD ruined by poor encoding.
