Well I did some more testing last night. If I set the 3250 to something
like the HD preview channel then do:

firewire_tester -R
firewire_tester -p -n 0 -r 5000

All tests receive packets. As soon as I switch off the preview channel
(using the STB remote) the tests start failing and I have to do a "-R"
before I can start receiving on the preview channel again.

When firewire_tester is working I am able to capture the stream using
"test-mpeg2".

Does this all come down to the "5c" flag being set on the channels I can't
receive over firewire? Is there any way to confirm that the 5c flag is the
problem on the channels I can't receive?
