 I run a mythtv box with a DCT-6200 firewire cable box, and I find that
 from time to time I have to shut down mythtv, run mythtv-setup, and change
 the plug (usually between 0, 1, 2) because the box or firewire bus has
 been reset and assigned a different id.

 Luckily, it is very easy to fix this problem, I just run plugreport and it
 tells me where the box is now located.

 Does anyone see a reason why we could not implement a function similar to
 that of plugreport that scans the firewire bus and tries to locate the
 cable box?  We could then have an option in mythtv-setup to just set the
 cable box GUID rather than the node/plug.

 We could even add a function to the mythtv-setup page that allows for
 automatic setting of the GUID for the first (potential) cable box found.
 This would also be a good step towards potentially supporting differences
 in cable box capabilities in the future, since at the same time we could
 probably detect which type of box the GUID is for.

 I think that having to set node/plug is a major drawback to the firewire
 functionality of mythtv, and that having it handled more automatically
 would greatly enhance usability and reliability.

 As we make these changes, we could presumably also add some more sane
 initialization to the firewire connection, such that having to do things
 like:

 "plugctl -n 1 oPCR[0].n_p2p_connections=1" (from the wiki)

 are not necessary to get it to work.

 I'd be happy to work on coding this up, unless it is already being worked
 on...
