Hello,

I am having choppy video and out of sync audio when playing mkv 1080p files with VC-1 codec.

Please help or point me to existing thread.

Win 7 Ultimate, i5, 8gb RAM, 1 gb nvidia optimus VC, 7200 rpm hdd.

Thanks Much.

One recent video problem turned out to be a problem with the antivirus software.

Thanks.

I'll turn bitdefender off and give it a try.

Just curious why and what antivirus does to the stream.

bitdefender does nothing to the stream
this might be the problem : 1 gb nvidia optimus = usually to weak on vc1 specially if interlaced and using madvr.
and like JimH says in the post above "One recent video problem turned out to be a problem with the antivirus software."

Ok.

What minimum specs to run vc1 interlaced and using madvr or other options ?

Thanks.

I think a nvidia 660/760 is highly recommended for madvr but you can try this :
Tools>Options>Video>Custom Video Mode Settings>Video Renderer and select : Enhanced Video Renderer
this might help
