Re: Make multiple avi files in one run

I think I've seen the CAviFile wrapper class you are using or at least a
variation of it.

If your CAviFile class has a AppendFrameFirstTime method that sets up the
AVI file, then it should reset the m_lSample (or lStart) parameter to 0.

BTW, sorry about the slow response, I didn't get notified of the reply for
some reason.
