Glad it's working for you guys. I have noticed something similar but
haven't tracked it down yet. Last night I was working on a patch and
was testing flagging on a few shows and then going into the editor and
seeing how accurate the flagging was. The frame numbers displayed in the
editor and the frame number that mythcommflag had were different. I
didn't go through the whole file, but at the beginning of the video, they
were off by 3 frames I believe. mythcommflag gets its frame number from
videoOutput->GetLastDecodedFrame()->frameNumber. Maybe it's something in
the null video driver, but it does cause frames to be off sometimes it
appears in non-DVB cases. These are MPEG2 recordings from M179 cards.
I'll continue looking, but just wanted you guys to know that something
like this is appearing elsewhere just in case you noticed you were still
off by a few frames.
