 I'm running Mythtv-0.22+fixes (svn20091118) - and have found that when
 mythtv-backend tries to generate screenshots of the things it has
 recorded, it generates MANY errors in the backend log, when making
 screenshots of recordings from DR Ramasjang (MPEG4 stream) and sometimes
 the screenshots has a lot of artifacts - see this example:
 http://vsen.dk/files/1004_20091127085900.mpg.100x75x64.png

 There's a link to a recording in #7637 from same channel, so this should
 be same problem.

 The errors in the logs are many lines of this:

 p.s. 0.22+fixes is missing in Version - and I can see from SVN that it has
 been created.
