True enough. Although it would be nice if you could tap into those
libraries and yet maintain control of the seeking. If you could just
get mplayer or xine-lib to skip to frame xyz on demand that would
probably do the trick. But you are correct that you do limit yourself
to some degree in this way - especially with stuff like
picture-in-picture, OSD, etc. Maybe the library providers would
entertain accepting patches to get them to behave the way you want, and
you could always fork in the worst case.

That's GREAT to hear! A transcoding option to preserve AC3 while
downsizing the video to H264 (or MPEG2 if you must) would be wonderful!
Again, I don't want to knock the great system that myth is. Especially
when the most I've contributed is a little patch to add an icon for
preserved programs to the program listing...
