Could you point me at an example (e.g., captured from your stdin) of a file 
that illustrates this problem?

Yes, please point me at an example of this data also.

The problem here is that the code's MPEG Transport Stream 'framer' 
currently assumes that MPEG Transport Stream packets begin at the very 
start of the stream.  For stdin, of course, that usually won't be the 
case.  I'll fix this....
