Can someone please tell me the frequency of the 1080i signal output by the Foxsat HDR ?
Thanks

What frequency ?
Not sure why you would want this info 
However max pixel frequency for hdmi 1.3 is here
http://en.wikipedia.org/wiki/High-De...edia_Interface
or do you mean the highest frequency receivable by the tuners (not related to HD or SD)
http://en.wikipedia.org/wiki/Ku_band

Sorry, yes I do mean over HDMI.
The reason I want to know is this. I have built an HTPC and the SD picture quality is not as good as from the HDR. I can alter the output from my Graphics card so I reason that if I can set it up as the HDR then if it isn't as good there must be another reason. At the moment I'm not sure that it's just that I haven't set it right.
Hope that makes sense.

Thanks for the links Graham, bit over my head I'm afraid.

It sounds as if you are confusing the horizontal refresh rate of the monitor with the frequency used on a hdmi digital interconnect which is related to the amount of data it's transmitting, two different things

Yes I'm sure you're right but if you could please read #4 you would understand what I am trying to do. And any help you could give would be most welcome.

Graham, just a bit more info. I'm viewing the pictures on a Sony KDL-40V4000 which must be pretty similar to your TV I think.

Normally you would use the highest refresh rate consistant with the resolution that the graphic card and monitor will support. At best the HD signal will only have 1920 x 1080 pixels. What goes to the monitor depends on what the graphics card does to a 720 x 576 (or less) 25fps interlaced source or a 1920 x 1080 or 1440 x 1080 HD source also at 25 fps interlaced. Same applies to a TV the picture depends on what it does with the same source signals.
In general broadcast TV looks better on a TV rather than a PC monitor which is designed to view from a much closer distance.

Well it's an ATI 5450 card, which I believe is quite a reasonable card and the TV is a Sony KDL-40V400. The card is set to output 1080i50 but the result is not as good as from the HRD and I'm trying to figure out why. 1080p60 or 1080i60 seem to make it slightly worse.
1080i / 50Hz input flashes up on my panasonic g20 when I select a HD channel on my HDR, if that helps

I assume that the HTPC has a satellite tuner card on board and you are using the same channel on both it and the Foxsat to compare quality?
If so then there is no reason why the two have to be perfectly identical. There is a shed load of processing that goes on in the electronics between the tuner and the HDMI lead. Unless your HTPC uses exactly the same gubbins as the Foxsat then it is entirely understandable why they should be different.
They are simply processing the data in different ways.
