[mythtv] New ieee1394 code and DCT-6200

I don't think its that the box is busy with something else, as I don't have
the DVR version.  Mine is just a cable-box.  I'm beginning to think that its
probably in the linux drivers for this, either the ieee1394 drivers
themselves, the raw1394, or the libiec61883.  I get this behavior, as I
said, with the test-mpeg2 utility outside of myth.  

I hooked the box up to my laptop and windows XP and used drivers I found on
the AVS forums.  I get a capture everytime I ask for it with that, so I'm
even more convinced it must be on the communication layer in linux.

I see similar behavior.  My suspicion was (is) that the cable box is 
being choosy about when to make a signal available.  For example, I 
think it doesn't output anything if it's recording anything itself on 
either of its two tuners.

To verify this, I am looking for another device to use for snooping the 
firewire bus when the Myth box is getting nothing.  I would be happy to 
learn that this is actually caused by bugs in the Myth stack somewhere.
