I see. I had noticed that seeking in an OGM file using the keys is very 
imprecise and unpredictable.

This is changing the topic somewhat, but is there currently any support 
for chapters or subtitles in a Quicktime container? I have been 
wondering if Quicktime would be a better container format than OGM for a 
movie with MPEG4 video and Vorbis audio. Quicktime4Linux/LibQuicktime 
and therefore Xmovie and Cinelerra can deal with such movies. Also, I 
understand that some variant or derivative of the Quicktime container 
format is part of the MPEG4 spec, whereas OGM with MPEG4 video seems to 
be pretty ad hoc, though supported by several players on both *nix and 
Windows.

Thanks for your time, and for your work on OGMtools, which I use frequently.
