So how do you go to high def capture, and isn't there only like 6 channels in High Def, i have HD on my cable box, but only Fox, CBS, NBC, ABC, TNT, ESPN, and one other channel come in HD, so wouldn't High-def capture capture at the same things for the other channels as the PVr-250's? Or is there a card out there that captures regular tv better? Also, i was thinking that a better ivtv driver, than perhaps the one i'm using, would actually look beter, Like it seems my old Tivo (i have the original with no subscription) looks better than a lot of recordings of my pvr-250's.
Than i'm confused, my TV can display 1080i and 720p (480p and others, but those are the two highest resolutions), so i thought 1080i was interlaced display, so if the video going over dvi was interlaced wouldn't that show fine as long as the dvi select was for 1080i? I'll admit i'm a bit slow when it comes to all this stuff with HighDef resolutions between tv and computers, so thanks for the help.

In a manner of speaking. It's likely the NTSC--both your PVR-250's
recording NTSC and your video card outputting NTSC. You can fix the
video card outputting NTSC by using a better connection (like
DVI/VGA/Component), but can only fix the PVR-250's recording NTSC by
upgrading to high-def capture and playback.

You will want to deinterlace all interlaced video you pass over the DVI
output. Normally, your TV would deinterlace the NTSC and any interlaced
ATSC video coming in through its tuner/component/S-Video/composite
inputs, but it simply displays the DVI signal as input. So, if you
don't deinterlace, you'll see interlacing artifacts since your TV is not
interlaced. The problem is the interlaced input--all your recordings
off PVR-x50's are interlaced because NTSC is interlaced.
Than i'm confused, my TV can display 1080i and 720p (480p and others, but those are the two highest resolutions), so i thought 1080i was interlaced display, so if the video going over dvi was interlaced wouldn't that show fine as long as the dvi select was for 1080i?
