Hey all. Well I have learned volumes about Mencoder int he last week. I
have everything the way I need it with Mencoder. I am using a 3 pass
encoding as you can see below. I let it do the default and skip frames if
needed and the audio is off right away, but it does not stray away until
it is literally over a minute off in a 2 hour video. The files I am
encoding are out of a Tivo. Res is 480x480 and sound is 48Khz. I am
wondering if I leave Noskip on but transcode the audio to 44Khz if that
will solve my problem? Or turn no skip back off and figure out how to setu
the audio offset?

Does anybody esle here use Mencoder to transcode Tivo MPEGS?

How do I tell lame/Mencoder to process the sound to 44Khz?

Thanks for all your help, past, present & future.

My current command line for highest quality. I change little things like
resolution or quality depending on how fast I need to encode something.
None of the things i change seem to effect the quality.
