 When mytharchive renames the output files produced by ProjectX, it will
 occasionally mix up the files and rename them incorrectly, resulting in
 failure during further processing. This happens because mythburn.py relies
 on the stream PIDs found in the ProjectX log appearing in the same order
 as the corresponding output files in the log. This, evidently, is not
 always the case.

 An example of this behavior follows. ProjectX finds the requested streams
 (video, audio, subtitle) in the following order (audio, video, subtitle):
   -> special PIDs for searching defined: { 0x12D 0x12E 0x12F }[[BR]]
   ok> PID 0x12E has PES-ID 0xC0 (MPEG Audio) (1504 #9) [[BR]]
   ok> PID 0x12D has PES-ID 0xE0 (MPEG Video) (5640 #31) [[BR]]
   ok> PID 0x12F has PES-ID 0xBD (private stream 1) (SubID 0x20)
 It then processes the streams in the requested order (video, audio,
 subtitle), although that may just be coincidental. The mythburn script
 then pairs up the first stream found (audio) with the first file produced
 (video) when renaming the files, so it renames the video file incorrectly
 and does the same with the audio file. I will attach the logfiles showing
 the exact behavior.

 A temporary fix would be to skip the rename logic altogether and use
 hardcoded renames from *.m2v to stream.mv2, etc. that are already used as
 a last resort.
