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:
deepthought:/mythtv/mythtv/recordings # mythtranscode -c 1700 -m -v all
