Ok, thanks Yraen.
I have a problem converting chcken little blu-ray to mkv. I get glitches in the 10 first seconds of the video. After that everything is fine. I made a
sample. Tried different decoders/renderers during playback, nothing changed.
When i muxed (to mkv) the complete source file, i got an error that haali muxer can't handle the source, and used -seektoIfrmaes switch. This error popped quite deep into the file, so i don't thing it's related. Sample doesn't make haali muxer complain, anyway.
