Comment:

 Glen I think you may have a different problem.

 The problem I'm seeing turns out to be due to the simplistic way we scan
 for pictures in the DTVRecorder. It picks up an extra frame whenever the
 sequence 0x0 0x0 0x1 0x0 occurs in the stream; even if the syntax is not
 right for a picture code to occur there. This same type of scan appears to
 always work with the ivtv recorder, but it appears to fail sometimes with
 the wild and wolly streams we get with DTV capture.

 Long story short, this isn't something that I can fix before 0.19, this
 requires properly parsing the stream and not just scanning for magic codes
 in the stream.

 Do I'm pushing this off to 0.20..
