Hi

On my i7 windows 7 laptop I run vlc (currently 1.1 beta) but happens on
all previous versions..

only seems to occur for certain encode videos.. and random blobs occur
on movement not all the time.. its very odd

but I dont get the problem with sharks007 latest codecs and using MPC player
on the same file.

here is mediainfo for the file

Im wondering if its to do with simple L3 profile as most xvids are adv L5 now days

You prob can converted any Mp4 file with a free program called Umile encoder 3.12
and create the same problem on playback.. it produces the artifacts sometimes
not always though.

but since other players dont show artifacts or bleeding I dont think its
the encoder

anyone else noticed this?

actually corruptions happens in kmplayer and windows media player 8
and xbmc for windows as well.

just dont happen in media player classic.. whats it doing different to
others

so its something umile encoder is doing that throws all except mpc.. very odd

will test same file via streaming to tv next to see if happens there

Not sure if this will help but I was having the issue since version 2 (and all updates since) at least. What solved it for me was:

Tools > Preferences (show settings "all") > Input/Codecs > Video Codecs > FFmpeg > Hardware Decoding (untick)

Seems some others on the forums had similar issues all linked to some sort of hardware acceleration option. At first I thought it was my GTX 260 Core 216 having artifact problems but I just got a 660 TI and it did the same thing until I found that option. I don't think it's CPU or GPU specific but perhaps something to do with FFmpeg.
