Ok.  I went through and cleaned up my config.... there were a couple of
transport entries I created when I was playing with settings.

Now I still don't get a picture and the lock error still comes up but my
packet capture does show the igmp join and the multicast stream coming
in.  I wonder if it has to do with how the stream is composed.   The
stream contains 2 video parts, one is a thumbnail size that the stb uses
in the corner of the guide and the other is the full resolution.

Here is the log info that is specific to this:

2011-02-27 09:17:11.987 Program #1 not found in PAT!
Program Association Table
 PSIP tableID(0x0) length(17) extension(0x109)
      version(2) current(1) section(0) last_section(0)
         tsid: 265
 programCount: 2
  program number   265 has PID 0x  20   data  0x 1 0x 9 0xe0 0x20
  program number 10265 has PID 0x  22   data  0x28 0x19 0xe0 0x22

I'm pretty sure in the case of this channel the 265 program number is
the thumbnail and the 10265 is the full resolution stream.
