ogg in CVE and CVO can have only vorbis audio. This is shortcoming of

Thanks, got it. For some reason I can't convert it to usable ogg. I have
to investigate this problem.
Flickering when moving manually is unrelated to file type. This is
problem in playback: for some reason it displays after manual moving
black frame which remains on screen until decoder is ready with the
right frame. Cinelerra decodes everything and applies effect on the fly
when playing back.
Wrote this problem to my todo-list.
