 When two shows are recorded one after another on the same channel with an
 IPTV recorder (I am using the TBS2603), the tuner isn't stopped and
 restarted, instead the ongoing stream is written to a new file.  Something
 in this second file prevents MythTV from seeking.  You cannot jump forward
 or back, and cannot use the cutlist editor.

 Using mythcommflag --rebuild does not fix the problem.

 I am attaching several lines of output of
 {{{
 ffmpeg -nostats -i <FILENAME> -vf showinfo -f null -
 }}}
 for the first (working) and second (broken) recordings, in case that
 helps.

 There isn't much to see in those files, except that it looks like the
 recording is transitioned exactly on a keyframe, which is good.  The first
 recording doesn't start on a keyframe, so there is, in this case, 0.87
 seconds of unusable data at the beginning of the file.  That's not a big
 problem, my keyframe distance is 1 second.  The other thing that's
 interesting is that the broken file has pts that starts at 0, while the
 working on starts at a larger pts.  However, if you allow for
 approximately 3003 pts counts per frame, then the missing frames at the
 beginning of the working recording should start at zero also.  Are there
 any other statistics I can provide to help?
