Bryan,  Thank You for the reply.

So i install dvbsnoob and ran it on a test-mpeg2 file.  When i Grep'ed for
"PID: 0" I got nothing.  I then did a grep for just PID.  Here is what I
see:

dvbsnoop -s ts -if test.mpg | grep "PID:"

Looking thru the file about 99.9% have PID 66 (0x0042) with a few being PID:
67 (0x0043)

So what does this tell me?  Will the patch fix it or do i need a diff fix?
