I don't have experience with capturing HD downconverted to svideo, but I
did spend a couple of years watching it that way before I got my HDTV
(the tuner was a much cheaper "try it out" expense!).
The quality should be MUCH better than what you see on regular basic
cable. After learning to love the picture of HDTV downconverted for my
standard def TV, I got a hipix card for an htpc to be able to record and
play back that way (I was already spoiled by tivo at that point). It
was very nice.
Robin> What will it do with widescreen satellite programming?
I believe it depends on the STB. Any of them will give you black bars
top&bottom (like watching a widescreen DVD), some may let you "zoom" the
picture (losing the left&right sides), a few may let you expand the
picture anamorphically (stretch vertically, which would get you the best
vertical resolution without losing parts of the picture). If you can do
this stretch, you should be able to use the aspect ratio controls in
mythfrontend to restore the aspect ratio (or watch it stretched if that
floats your boat!). IIRC my dish 6000 can do that stretching, but I
haven't used its svideo out since I got my HDTV last year.
If you have the chance to check out some receivers at a local retailer,
that should get you a definitive answer.

I think if you can verify the receivers' capabilities, it'll be worth
doing. If you're uncertain, choosing a retailer with a return policy
would be wise.
