Re: Lost frames, or what else?

Hi Andrea,

My dropped frames, which numbered more than 5, occurred at about 01:44:15 on
the capture. I confirmed this by reviewing the captured video. I am not
certain if frames were dropped before this, but I recall batches of frames
being dropped after this at other times. Unfortunately I cannot reproduce
the capture any longer. But as I said before, when I re-captured to another
file, the same number of frames were once again dropped at the same place.
