Thanks John - that pointed me in the right direction. Unfortunately  
it didn't fix my issue.

Since you seem to be the firewire guru, I have a issue that you might  
be able to solve...

I've got a DCT-6200 and 14 HD channels on my plan. MythTV has no  
trouble tuning 10 channels. The other 4 are on a special HD package  
from my provider and are a little problematic. Before .20, if MythTV  
could lock to the broadcast stream on one of the 4, I would get about  
a minute of broken up picture before the backend would just stop. At  
the same time, the backend log would fill with TS packet out of sync  
errors. Now with .20, I see FireRec, Error: TS packet out of sync but  
the backend doesn't crash. CPU usage is not an issue

I checked the service menus on the DCT-6200 and none of the channels  
has 5c. MythTV seems to like broadcast mode at 200 Mbs.

I tried to recompile the kernel (2.6.17-2174) with your dma.diff  
firewire fix (hand edited it as the diff doesn't like the current  
kernel), but the compile kicked and error when it got your last  
change (too many variables?).

So, would the firewire kernel fix help this? Any other words of wisdom?

Thanks in advance.
