From an audio site:

"However, DVI does not pass digital audio signals as HDMI and a separate audio connection is needed for the audio". DVI stands for Digital Video something or other, no audio.

Yes, I don't have a splitter. The cable coax comes into the house and is plugged directly into the cable box. Then HDMI out from the cable box to the TV. Audio out from the cable box to the tuner. The sound is turned off on the tv. I listen to audio thru the stereo. Then DVI out from the DVD to the TV. And also audio out from the DVD to the stereo.

>I have a DVI to HDMI connection from the DVD player to the HDTV. (Acronym vertigo!) I bought a new DVD player from Oppo -- a company to watch -- that is designed to take advantage of HDTV and has won awards. It's the TV broadcast side of things that is flummoxing me at the moment.

>When you say you have an antenna going to the cable box, do you literally mean an antenna on the roof, or a coax cable?

>PS -- DVI is the format that contains both video and audio. HDMI contains video only. One of the nice things about the Oppo DVD player is it comes with both kinds of connector. I believe they both sell for $60+ at Best Buy, so that's pretty nice throw-ins with a $200 unit.

>>I don't have a DVR. I've had the antenna going to the cable box for a long time, due to scrambled channels.

>>My setup is
>>1) antenna to Cable Box
>>2) There are 2 new types of connectors meant for HD - DVI, HDMI. My understanding is that HDMI is the newer format. It contains both audio and video. If you use DVI, you will still need to run separate audio cable.
>>3) My tv has 1 DVI input, 1 HDMI. I use DVI for the DVD player, with DVD audio going to my tuner. And I use HDMI for the output of the cable box.

>>FYI, my experience jibes with other's I've read about. Because HD TV's are developed for HD, they will show defects from standard broadcast tv. If I watch the HD version of Fox (tv channel, such as 24, never ever Fox news), it is 1000% times better then the standard broadcast version of FOX.

>>Of channels 2-13, all but 2 I receive have a HD version broadcast on channels 190 - 200. I hardly ever watch the 2 that don't have an HD version anymore.

>>>Two weeks ago I decided to take the plunge into HDTV. So far, not so great. I wondered if anyone here has some expertise with this stuff, which I do not, and can give me some advice.

>>>Here is the high level description of the problem. I have cable TV and the cable goes through a splitter, one part to the cable box and the other directly to the TV. The cable box side of the equation has one additional component, a TiVo DVR. So that cable goes from the wall, through the splitter, to the cable box, to the TiVo, to the TV. When I watch the TV in native mode, straight in from the cable coax, the picture is fine. But when the signal goes through the cable box and the TiVo before getting to the TV, it's pretty crummy. Actually worse than the picture on my old TV. This would be quite a bit of money to spend to get a worse picture.

>>>I suspect I know where the problem is, or at least part of it. The cable box to TiVo hookup is via RCA connecters (yellow video, red and white audio). My dim understanding is those are artifacts of the analog, 480 line, interlaced scan world. The connection from the TiVo to the TV uses an S-video cable, so that shouldn't be a problem. I bought an additional S-video cable and connected it from the S-video port on the cable box to the S-video In port on the TiVo, but the TiVo said it wasn't getting a video feed. The port on the cable box is not clearly marked so maybe it's supposed to be input, not output.

>>>IAC, any suggestions? What cables should I be using? Are there any likely video settings to tweak on the TV or TiVo?
