 In my DVB-C cable system are TV channels that cannot be recorded by
 MythTV. However, they can be recorded with gnutv and the resulting
 recordings can be played by MythTV when placed in a Video directory.

 Analyzing the streams recorded with gnutv shows that there is a private
 data stream with stream_type of 0x80 present. This stream is erroneously
 identified as an OpenCableVideo stream in MythTV.

 This problem has been identified before (see #2556 and the thread
 http://www.gossamer-
 threads.com/lists/mythtv/dev/231271?search_string=opencable;#231271) and
 the fix was to use the first identified video stream as the real video
 stream. This worked because in #2556 the 0x80 stream came after the real
 video stream. However, I have TV channels where the 0x80 stream is seen
 first so this does not work for me.
 [[BR]]
 I've fixed this by adding a new IsVideo function that also checks that the
 sistandard is "opencable" when the stream_type is recognized as
 OpenCableVideo (0x80). I have also changed the test in StreamID::Normalize
 to check explicitly on "opencable".
 [[BR]][[BR]]
 There are changes in mpegstreamdata.cpp, mpegtables.h and mpegtables.cpp.
 Patch is attached.
