Hi,

I've been following a LOT of guides on how to upscale DVD's with ffdshow. I've also read through forums until my eyes started bleeding, but haven't found anyone with the same problem.

It works, but I get terrible pixelization on my 42" plasma not matter what. I've tried lots of settings, like LSF, Seesaw and so on. Has someone else experienced this? Even if I just resize and not apply any other filters or things like luma sharpen, I get this problem. I've also tried to use PDVD7 for decoding and ffdshow raw filter as processing, same result. With MPV ffdshow won't even load. Any ideas? I really like the quality with upscaling, is does a huge difference, but the pixelization really sucks.

Thanks.

Does the pixelization only happen during fast motion? or all the time?

It's there all the time, but it gets worse during motion.

Are you dropping frames during this time? (shouldn't be with that proc)
Does it look like digital artifacts? Like with a bad digital signal? or something else?

I have never really heard of pixelization during ffdshow upscale, but issues with deinterlacing...

No, no frames dropping, CPU load is at about 10-20%. It does look like digital artifacts, I think. Atleast that's what I would call it. Hard to describe really. It's like a "blocking" effect, where the blocks seems out of sync, creating jagged edges and also vertically unsynced lines. I haven't been able to find anything about pixelization with upscaling either.

I did a small experiment and tried playing a mounted image file from the harddrive. This seems to get rid of the problem. I then tried to play a DVD (no copy, original) in my DVD-burner and the problem was there again. So it seems my DVD-burner (NEC ND-3540A) is to blame. Never heard of such a thing, but it seems to be the problem. Going to try some more things to verify. Thanks for the input Dubyahjay

I hope getting a new optical drive can cure this problem.

That sounds like a more likely culprit, similar to losing parts of a digital steam (or it becoming corrupted). For instance, when my sattelite signal is partially degraded due to rain etc. Let me know how things turn out.
