I bought some DVDs, and feared that they might be scratched, so I wanted to
store the content on hard drive. I did
mencoder -voc copy -aoc copy dvd:// -o output.avi
then I found that the audio and video are out of sync, the video is too
fast, by about 10%.
then I did some google search, and this seems to be a common problem, and
many posts point to using some combination of the 3 params:
" -mc 0 -noskip -vf harddup "
I tried all 8 combinations of them, but the results are still the same.
interestingly, if i swap the position of -noskip and -mc 0, the results are
without params, I can see the error msg "duplicate frame detected" when
mencoder was running. with -mc 0 -noskip param, the error msg is gone, but
my video is still out of sync
