Tvheadend

DVB-S / DVB-S2 recordings seem to be broken when recorded with tvheadend. There may be a defect header info, that causes xbmc and ffmpeg to crash with a floating point exception.

Other applications cannot play that video file either.

The problem does not exist in version 2.11, but it is definitely in the builds from subversion revisions 5314 and 5335.

Here are sample outputs from ffmpeg and mkvinfo:

ffmpeg -i somerecording.mkv -acodec copy -vcodec copy -f mpegts somerecording.mpeg
