I’m currently researching a new HDTV and home theater system purchase. I’ve narrowed my video signal choices to a Comcast Dual Tuner HD cable set-top box and a progressive scan DVD player. I’m considering a Panasonic industrial model HD plama panal TH-42PHD7UY. One strong reason for this choice is that I can’t figure out why I should pay the extra cost for an integrated tuner if I’ll already have the Comcast box to tune cable channels. The problem that I have is that both the Comcast STB and the progressive scan DVD player I picked out offer the highest quality Video Out signals (DVI-D and HDMI respectively). However, A/V Receivers are typically only capable of switching video signals at the component level (short of spending $thousands$). Thus it seems my available options are to accept the component level connections and switching, and send a component level output to the TV (this seems a bit sub par), or, figure out a way to take the two highest quality signals directly to the monitor and figure out a way to switch video signals there. Option two probably means buying two HDMI interface cards for the monitor and relieving the A/V Tuner of all video responsibilities.
Any input on how I might untangle myself from this system design delima would be greatly appreciated.
