I haven't found anyone with a usable 1080i. Do you know which drivers worked? Which list archvie were you referring to: nvidia or mythTV? Any CRT that takes 1080i should also take 540p. The only differences are in the timing. Of course, LCD and plasma have to digitize and rescale everything; so they might act differently.

It's interlaced over DVI that doesn't since it uses the normal monitor output. Its a known bug that NVidia won't fix since relatively few people use it.

LCD and rear projection have very minor overscan which is nice, its the tube TV's that exhibit obscenely large overscan. Plus, with TV content your missing with Myth what you'd miss without it, so its a wash really.

So far I've had great luck with the TI chipset in my laptop, no problems with it. I had a VIA on my Myth motherboard that just refused to work, and from what I've seen the people with VIA chipsets aren't having much better luck than that. I ended up getting a card from newegg(a Syba with NEC firewire chipset) for that computer that I've had, I'd say 95% success rate with (just in channel changing, haven't setup firewire capture yet). When I get back from Vaca. I'm getting another cable box and will have one capturing via firewire and one via PVR150, so we'll see how that goes. My advice rght now is to stay away from Via and be willing to spend a few bucks on a quality firewire card. I also found that some of the packaged libraries seem to not be perfect, I ended up compiling from scratch and my success rate went way up, same library version. > > Thanks again

[mythtv-users] Struggling with Xwindows DVI to HDTV 1080i
I've got an nvidia 6200 with DVI out connected to my Mitsubishi HDTV (DVIS to HDMI cable). The TV does 720p and 1080i on HDMI: it's worked from both the cable box and from a DVD player that does upscaling. I can get the TV to recognize that it's getting 1080i input from the computer. (The info on the screen says so.) I can't get it to deal with 720p for some reason. I can get the TV to handle lower resolution SVGA and XGA modes up to 1024x768 fine. With 1080i I get what is close to the twm screen, but there are two problems: 1. The screen is greatly overscanned. Perhaps 20% is not displayed. 2. The interlacing is off, or at least that's my guess. Everything is displayed twice, with one flickering image directly below another. They are close: the bar at the top of an xterm has its two images overlapping. I've tried every modeline I can find, and have tried two different modeline calculators, but I can't get the two images to converge. The TV seems to be reporting things correctly to X (59-61 Vsync, reasonable Hsync, etc.) Telling X to ignore the TV's info doesn't help in any case. It seems like it should be easy enough to play with the vertical blanking interval to fix this, and that I'm close. But I'm guessing, and I'm not making progress. Is there a reasonble way to tweak the modeline to iterate toward a solution here?
