Comcast HDTV???

The Box your getting is the probably the Motorola 5100. Its has component, S and composite video as well as Toslink, Coaxial and analog rca audio. Component cables are needed for high def TV and I would recommend going toslink , as I have , for the audio. I have read other forums where some people had problems going coaxial for audio. As far as the high def picture, last night I watched the superbowl and the Hi def picture was awsome.

Thanks for the input, When I'm up and running, I'll add a comment on percieved picture quality. On local comcast, there is no upcharge for HDTV, just a $18.95 ''Installation'', for dropping off the box. We get ABC, NBC, and PBS, CBS is still being negotiated. Programming, of course, will vary. HBO and Showtime are available in HDTV. The main reason I'm upgrading is that the standard digi cable box by General Instruments is such a piece of junk. Composite video only and RCA audio that isn't very good. We'll see what comes of the new one. One question: Why Toslink? Ground loop issues? I've always had better luck with a nice RCA 75 ohm digi cable.

Thanks again.

you can pull in digital and hd signals with a $80 vhf antenna from radio shack and tell comcast to cram their scam.
when i investigated this some time ago i discovered you have to first get digital cable (more $), then rent another "box" (more $$$, remember those dumb things they insisted you needed even when you told them you had a cable ready tv?) and then you get to watch hd when it is available on one major network and pay more $$$ (AGAIN) to have access to hd content on hbo and showwtime. sounds fun, like extortion and water torture.
they simply don't have enough non-premuim content yet to warrant the expense, butthis is just my 0.02
maybe things have changed or are about to (my eyes are rolling double time). i'll believe it when i see it here in philadelphia...
(btw, not a single person i talked to from comcast could plainly answer any questions about hd signals, broadcasts, etc that my father or I posed...either they are complete idiots or they have no interest in the public really understanding the facts about digital and hd television (that's it...i knew i'd get it sooner or later)
ymmv

Fujindemon,

Yes comcast is evil incarnate, unless compared to some of the other cable companies I've dealt with. The employees are pretty clueless. I tried an antenna with a roof mount, but I couldn't even get regular network TV. I'm out a in valley by Chester Springs (Far north Chester County), and we get nothing through the ether without effort. I need the roof antenna just for FM. I had digicable already as a package with the cable modem and the HDTV does not cost extra. Yeah, and I'm sure it will take three phone calls to get the bill straight. Oh well, sure is pretty out here.

Some people have said they have had audio drop outs with coax, although you may not. Since you have to move a large piece of furniture , I just thought I would give you a heads up. I have it connected with a Wireworld glass toslink and the sound is incredible. Even many non HDTV programs are presented in Dolby Digital. I use a Cardas Digital lightning coax for music.

As far as buying a cheap Radio Shack antenna, you would have to buy an HDTV {not cheap} tuner 1st.

As far as Comcast not being able to answer questions, thats because the people you speak to on the phone are just {no disrespect} clock punchers. Most do not know the difference between HDTV and HGTV. Their is a wealth of information on www.AVSForum.com
