What error messages?

I've found "mencoder" (part of mplayer - available in the current CVS). to be 
very good at re-encoding VDR's recordings.  I've only tried it with divx 
output, but according to the documentation it supports other output formats 
using ffmpeg's libavcodec.

For example, to use two-pass encoding to re-encode the video to divx and copy 
the original MPEG audio, I use:

mencoder -pass 1 -divxopts br=1500 -oac copy -pp 0x20000 001.vdr
mencoder -pass 2 -divxopts br=1500 -oac copy -pp 0x20000 001.vdr

The resulting quality is very similar to the original MPEG-2.  If you want, 
you can also re-encode the audio to mp3.

You need to follow the instructions available at
