[mythtv-users] MythPodcaster Errors When Transcoding (Ubuntu 10.10)

[Dave Pearson]

  Just before upgrading to Ubuntu 10.10 I set up MythPodcaster and had 
it transcode one TV Program for me. I have now upgraded and I cannot get 
it to transcode any programs at all. I'm sure it's probably a simple 
thing, like the wrong version of ffmpeg or missing an ffmpeg codec, but 
I've searched on google nad failed to find a solution to this problem 
(I'm sure I can't be the only one suffering!).

This is the log file showing the error:

Can anyone see what is wrong and point me at a resolution?
