Decoding interlaced XviD

I can only assume that your tv is NOT PAL,or else you cannot see properly interlaced material anyway.Maybe some post-deinterlacing would help.Did you try any of ffdshow's deinterlacing methods first to see what happens?You have a lot of options there,even with Dscaler dlls... regards, george

TV is NTSC. My understanding is you're allowed to horizontally resize interlaced content as long as you keep all the vertical lines. (720x480 -> 640x480, simple AR correction). When you use TV-Out with a hardware overlay, the TV can process an interlaced signal (like it normally does from a broadcast antennta, your VCR, your DVD player, etc.) and deinterlace it on the fly. I could use ffdshow to perform some rough deinterlacing, but if I wanted rough deinterlacing, I could attempt a hybrid deinterlace with decomb. A truly interlaced source should display correctly, deinterlaced, on a TV. I'm moving today, so I can't spend a lot of time searching the forums here for the background to some of these claims, but when I have a minute, I'll give you links to posts to back these statements up. (Or you can search for yourselves, of course. :))

It does not always work or look good IMHO. I have tried this and most times fast motion scenes that are interlaced look bad even on my TV using TV-out. If you know how to deinterlace right you should beable to deinterlace without ruining your quality. just my .02

I'm an experienced encoder, and as many will tell you, Star Trek: TNG DVDs are so badly interlaced that there is no perfect solution for making a progressive stream out of them (consult: ). As for resize horiztonally, avih posted "the width doesn't matter, but the height MUST be EXACTLY 576 for pal or 480 for ntsc." here: Also check that same thread for a few notes about watching interlaced XviD on a TV. Now that we've established that I'm not an idiot :D can anyone help me? :)

I think the main problem is the tv out. Your Ati Radeon 8500 does not output to the tv exactly 480 for height. That is why you see the interlaced lines. If u resize the tv out, and move it tot he right spot, then maybe it would work. *shrugs*
