Bad MKV extracted video stream

[jangai]

Acustomed to convert MKV x264/Ac3 files to AVI XviD/Ac3 720p with Graphedit filters chains piloted in AVIsynth script open in VirtualDubMod without great problem on MacBook Pro under Win XP Parallels virtualization or native Boot without great problem... (Only audio video/sync uneasy sometimes...)

I just get a brand new 8-core bi-xeon MacPro and after installing (apparently) same ressources on it, I get a bad video stream extraction (as you can see below) with images inverted and duplicated in the upper half of the picture surface... I have tried many "codec revisions", install/uninstall, version control aso... without any good result... Image is likewise distorded as well seen into graphedit render pin as into Win Media Player or into WinAVI converter preview... Tests has been made with several files and input videos are good looking with direct MKV playing with VLC !

Problem could be located in MKV extraction, but I'm not sure of anything...

Corrupted stream :

Thanks in advance for your ideas... :confused:

I can hardly understand what you are trying to say, but let me try - this "corrupted" stream, is that after converting to Xvid or is it this way even when you preview the avs before encoding?

Sorry for nebulous text... :eek:
This corrupted stream is produced as soon the MKV file is demuxed...
Example : I demux the MKV stream in a video file and an audio file : Video file open in Windows Media Player is as shown bye the screen copy into my first message...

It seems that it is MXV Toolnix or its "extract GUI" which does this bad job...

After deinstall reinstall of the last releases of MKV Tools : problem seems solved!
Video is well rendered into Graphedit directshow filters and into Windows Media Player (not in WinAVI Converter, but not the same deformation)...

Thank you for your help
