To make it clear, I've not used mencoder in the following scenario -
just posting to see if you think it would cope:
I've seen lots of corrupted mpeg2 transport streams (from digital
terrestrial in the UK), where corruption due to signal loss produces an
audio/video glitch. The result is a stream which will maintain sync
across the glitch when directly played back, but when transcoded with
whatever tools I've tried, including those meant to repair sync issues
(& often do a reasonable job), will still contain some sync issues after
Are you suggesting mencoder would be able to cope here? If so I'll try
it next time I see this problem.

Put the responses in a faq & just point posters there, or even put the
faq link in your sig for this list?
