For this one, there is no packet on PID 2340. Probably the demux 
filter wasn't set properly.

The mpeg_audio decoder receives packets but can't find a frame start. 
Maybe the unit_start_indicator isn't set properly, or there is no 
MPEG frame in there.

Note that the stream type of both streams is 0x3 (MPEG1 audio), 
whereas in the cases of satellite radios I know, the stream type used 
is 0x4 (MPEG2 audio).
