I record programs from cable tv through a DC10+. The quality is good
(MPEG2) but sometimes the video freezes. It comes from the broadcast
provider and not from my hard nor software part.
So the recorded video frames are correct, but with some frozen frames.
(~50 to 100 frames)
I would like to be able to detect them after the recording without viewing
myself the video.
VirtualDub nor VirtualDubMP3 nor Womble are able to detect this
problem.
These frames are necessarely detected during the MPEG compression
process by the codec.

The VirtualDub MultiDecimate filter, even if it is not designed to fix this
kind of problem, could do this but I need to play in real-time the whole
movie.

Is there a tool to detect such duplicated but correct frames in the MJPEG
or MPEG file ? It could return me the list of numbers of duplicated frames.
Does an environment exist (like AVISYNTH) which allows me to write a
script with functions like "NextFrame" and "CompareFrames" ?
