Thanks, that helped a lot.
There's just so much to think about.

Another question I have is comparing HD cable to Standard cable...if both were sent to the TV via S-Video would the picture end up being the same in the end?

I'm wondering because I would like to ask someone at Circuit City to show me how the tv looks with an S-video cable instead of the High Def that they are using to display the tv. But if the HD broadcast they send will look better even thru s-video it's not really helpful.

And since not all channels are in HD yet, do the standard cable channels (480 resolution) that are sent thru the hdmi cables still look as "bad" as the ones sent thru s-video from standard cable?
