Help! Blue and Red Blocks with XVID playback

I did a search and didnt find anything similar to my problem, so if this has occured or is a common problem, i apologise for posting. Here are some screenshots, i had to use the digicam because screenshots dont work too well with overlays. The same red blocks you see on the screenshot are also mixed with blue blocks most of the time, just difficult to capture because they appear and disappear in different spots so fast. I'm running Win XP now with a Geforce 2 GTS, 1,33 Athlon, ran Win2000 before that. I've tried using ffdshow or different xvid codecs. nothing changes. I put postprocessing up, no difference. When i switch off overlays (with BSPlayer e.g.)the blocks are gone, but i get horizontal lines when playing back. All my DivX movies play fine in Overlay mode 1 and when i set the Xvid movies to DIVX with AVIC, the blocks are gone too. So it seems to be a decoding problem... any help would be greatly appreciated.

Read up here:

ok here's some more info: using: Koepi XviD-04102002-1 _ALPHA_ Release either XviD-04102002-1 _ALPHA_ Release or ffdshow as DS Filter it doesnt matter which i use, i'va also tried others. it doesnt matter whether post-processing is on or off. PC: Windows XP SP.1 (had win2000 before, same problem) Athlon TB C 1333 Nvidia Geforce 2 GTS 64 mb I use BSPlayer mostly, there this bug occurs when i use overlay 1. When i use WMP 6.4 bug also occurs. When i use PowerDvD error also occurs Using WMP 8.0 the error is not there... This bug occurs with every XviD movie I play. When i change the fourcc to DIVX and let DivX decode, the error is gone.

someone? help!!! :(

Well that's certainly odd. What happens when you disable the overlay, or just play through VirtualDub? If the bug disappears when the overlay isn't used, there's not much we can do. -h

yes it disappears when i disable overlays and in virtualdub i dont have it either. But when i disable overlays i get some horizontal interference from time to time. And DivX plays overlays just fine...

Could you post a shot of the horizontal interference? I'm afraid there is nothing I know of that can fix your XviD+overlay issue - all XviD sees is an address in memory that it writes the image data to, it doesn't know if it's RAM or the overlay or what. How about playback via ffdshow? -h

strange thing with the overlays. these horizontal lines without overlay appear when there's fast motion in the picture. can't seem to be able to capture it. but usually a 1,3 GHz + Geforce 2 GTS should be enough to keep up with decoding fast motion right? P.S. when not using overlay i also get those horizontal lines with DivX, so thats not a XviD problem. These red and blue blocks seem to have something to do with xvid since i dont get them with DivX.

Could it be a tearing issue because your graphics or directx drivers are not syncing updates with vertical refresh? - Tom

I get blocks too!
