Howdy Julius,

My searching of the mythtv mailing lists turns up the following, which
might be of interest:

http://www.gossamer-threads.com/lists/mythtv/users/438891#438891

According to a previous ticket
(http://www.gossamer-threads.com/lists/mythtv/commits/421012) this may
be caused by partially corrupted stream (which myth handles ok, but
presumably transcode does not).

Please feel free to search and/or post on the Mythbuntu forums:
