ffmpeg cannot find mpeg2video in my SageTV recordings

[gallatin]

Summary of the bug:
I have found that some of my SageTV recordings are not playable in xbmc. I've traced that back to ffmpeg not finding the mpeg2 video portion of the recording.

How to reproduce:

%  ./ffmpeg -i sample.mpg

Note that there is no mpeg2video stream found. Other programs, such as mencoder and vlc are able to find the video stream.
