I have a nvidia geforce 5200, using svideo out. Mythtv looks sharp and very nice looking. However playback is still not that great. Not really sharp like the menu. I've played with the XV picture color controls, and tried kernel, bob, and liner deinterlacing techniques and nothing looks as sharp as that. Is it because it's deinterlacing the video? or because of the ivtv driver for the 2 pvr 250's i have?
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.
I've seen 5200 with dvi outs (like this, but this is 5500, http://www.newegg.com/Product/Product.asp?Item=N82E16814130197), i have a 52" lg dlp tv with dvi input, my cable and my dvd player go to the 2 composite inputs, would getting this video card could i then run it in progressive so no deinterlacing required?
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.
