For MPEG SP-TS You need the PCR_PID, PAT (PID 0) and PMT otherwise no 
decoder can tell what Video and Audio Pids it should decode. Translation 
an incomplete Transport Stream to PS will not help. In addition the PS 
will probably also miss some crucial MPEG PS header information.

The stream misses some crucial PS header information and is looking for 
a start code, which it does not find.

We have the same issues (kind of) with DVB-S cards and are looking into it.
