 The algorithm is naive in that it is just searching for certain bytecodes
 instead of parsing the stream. This will still always work with PVR-x50
 output, and still works with 99.9% of DVB/ATSC/QAM streams.

 If you want too look at getting the remaining 0.1% to work, have a look at
 #799, it points to some sample streams via other tickets it points to. One
 way to make those work would be to use ffmpeg to find the frames, another
 would be to look at their code and extract the relevant parts, and finally
 you could buy copies of the relevant MPEG standards and implement
 something based on that.
