I used to be able to transcode them in 0.20.2 which would greatly reduce 
the filesize of a 2 hour show (reduced from 1.4GB to ~370MB).  
Transcoding of radio shows always fails now in 0.21.  Transcoding also 
had the advantage of being lossless whereas the dvbradioexport.pl 
decodes the original recording and re-encodes it.  Not the end of the 
world but if I can avoid a re-encode I'd prefer to.

In case anyone has any suggestions the output of an example transcode as 
follows:
