I've read many of the posts here and I'd like to ask some questions. I am about to take delivery on a 38" Loewe Aconda that has one component input and one VGA input for high def signals. I do not currently own a STB or PVR. Is not the issue with DVI that if I currently owned a PVR without a DVI interface that I couldn't record a HD signal, and that if I currently owned a STB without a DVI output then I couldn't hook it up to a HD-PVR? But if I got one of the new combo STB/HD-PVR boxes being announced (Zenith just announced some today at CES) then I could hook that unit up to my Aconda using it's VGA or component output? In other words if I got the right combination of STB and HD-PVR then I would be alright even if my HDTV doesn't have DVI or FireWire? Sorry for the simplistic question.

Most HDDVRs will have component video outputs for a while, so no DVI is necessary to get the signal to the TV... __________________ 57U - Toronto, Rogers Cable, SA8300HD, 500GB HDD & Hitachi 61UWX10B HDTV, Yamaha RX-V1 A/V Receiver, Martin Logan Speakers.

Thanks 57U. I guess what I'm driving at is that if one gets a "next-gen" combo box that has an HDTV tuner and a HD recorder built into it together, then does one need to worry about DVI/FireWire at all?
Yes, I understand that if I wanted to record to tape using a DVHS deck then I would need to worry about DVI/FW. I'm not too worried about that. I want to time shift HD programs, not archive them. If the program is any good it'll come out on DVD with cool extras anyway. I just want to be able to timeshift an HD program that airs on Thursday night (that's my drinkin' night!) and watch it, in HD, on Friday, using a "combo box" feeding into my TV using the VGA port.
For reference the following is information from Zenith, who just announced some combo boxes.

HDR230 HDTV Receiver/Personal Video Recorder combines Zenith’s latest-generation ATSC terrestrial tuner with an 80-gigabyte hard disc recorder — allowing storage and playback of more than eight hours of HDTV programming — for an irresistible marriage of performance and convenience. Features include basic on-screen navigation using a PSIP-based (Program System Information Protocol) electronic program guide, Dolby Digital® recording, live pause, variable rate trick play, a variety of fast- and slow-motion capabilities, record file management, aspect ratio control and high connectivity via RGB, Component, S-Video and A/V outputs. The HDR230 is expected to be available from Zenith dealers in the second quarter at a suggested price of $999.

There are no concerns about wiring with "combo boxes" since there is an internal connection between the "tuner" and the "recorder". The same holds true for "combo" satellite and cable boxes about to come out soon. The cable (not sure about satellite) combo boxes would typically need to be rented or purchased from the cable company and activated by them. Cable companies typically do not "activate" equipment that has not been supplied by them. You can't simply buy a STB and hook it up to cable. That's why my previous post talked only about "separate" HD DVRs __________________ 57U - Toronto, Rogers Cable, SA8300HD, 500GB HDD & Hitachi 61UWX10B HDTV, Yamaha RX-V1 A/V Receiver, Martin Logan Speakers.

Away from big buildings and in a three story house. I'm sure I'll be able to get OTA. AT&T Broadband hasn't made any announcements as to whether they'll be doing HD yet. Is the worry that if they do roll out HD that their cable box would have to connect to my TV with DVI? (For HD signal.)

There are a lot of HDTVs out there without DVI. Perhaps in some number of years, new STBs will no longer have component video outputs.... For now, DVI is simply another way of getting signals to the TV. DVI is digital while component video is analogue. Some people have said that DVI is "clearer", but others say they saw no difference. __________________ 57U - Toronto, Rogers Cable, SA8300HD, 500GB HDD & Hitachi 61UWX10B HDTV, Yamaha RX-V1 A/V Receiver, Martin Logan Speakers.

At this time my lack of a DVI port will not be a problem, and I could hook up several of the combo HDTV/PVRs that were announced at CES, such as the Zenith or DirecTivo units. But some day down the road the content providers may flip a switch and the only way I'll be able to view the content recorded on the box is in a low-res. On that day I'll be in court filing a lawsuit. Laveller, in my limited research I have not seen such a converter. Perhaps some one will invent one. I get the feeling it would require some computing power, though.
