Hrm.  Even using HandBrake I still get a file that only plays now for 10
minutes.  Here's my HB command line:

HandBrakeCLI -i /storage2/3093_20150215155900.mpg -o /storage2/3093_20150215155900.mkv -f mkv -e x264 --x264-preset faster --x264-profile high --x264-tune film -q 21 -E copy --decomb --crop 60:60:0:0 -w 720 -l 360

And when done, I rebuild the seektable:

$ mythcommflag -v all --loglevel debug --nologserver --rebuild --file /storage2/3093_20150215155900.mkv
2015-02-15 20:32:26.923610 C  mythcommflag version: fixes/0.27 [v0.27.4-4-gb305eb5] www.mythtv.org

And when I play in mythavtest it now thinks this 30 minute file is only
10 minutes log when Mplayer is perfectly capable of playing the full 30
minutes long.
