Use Vegas.SelectionStart, Vegas.SelectionLength, and Vegas.LoopPlayback.

Markers and Regions can't share positions. Try to offset the beginning
or end by a single frame.

For now, yes... scripts can't have things changing beneath them.

For now, no... scripts need to execute on Vegas' main GUI thread and,
as mentioned above, can't have things changing beneath them.

Updated docs, faqs, etc. will be available when Vegas 5 is released.

I was busy with new features for Vegas 5. I'm back now.
