Comment (by danielk):

 The "firewire-sm-v10.patch" patch still has some problems.

 1/ To deal with internal buffering in the STB we pause for 5 seconds
 before trying to check the data we are getting. I haven't found a way to
 reset my STB reliably, but I'm still testing potential solutions for this
 problem.

 2/ If the firewire bus needs resetting this version of the patch does not
 perform the reset. I need to add some safety checks to this code and make
 it optional. The point of the reset is to be able to leave encrypted
 channels if we accidentally change to one (important durning a channel
 scan).

 3/ I haven't added any channel scan capability using the firewire signal
 monitor. But the plan is to add this so that firewire setup is a little
 more automatic for users where some of the channels are encrypted.

 4/ So far this is Linux only, I'm working getting a Mac development
 environment working so that I can add support for OS X as well.

 5/ The firewire recorders really need some refactoring after adding signal
 monitoring, I plan to do this after I get that Mac development environment
 up and running.

 Otherwise I've been running a version of this patch for a couple weeks and
 it seems to work ok other than the longer channel switching time.
