This could be more to do with the lack of correct seek support for AVCHD
H.264 MPEG-TS in ffmpeg.

I've been in correspondence with Ivan Schreter about his recent seek
patches added to ffmpeg, since when I tried them they totally broke
playback of Canon HF11 MTS files PF24-in-60i encoding. He developed them
against his Panasonic camera's MTS recordings.

My current ffmpeg package is from the ffmpeg git prior to Ivan's patches
because they made the system unusable.

I'll see if there's any improvement with the latest HEAD.
