#9284: MythTV 0.24 fails to start playback after channel change on firewire STB

 I have attached the output of mythfrontend --version and mythbackend
 --version. I have also attached a diff from two changes to the firewire
 related sources to add in the vendor and model IDs of my Motorola
 DCX-3400-M STB. These patches are the same in 0.23 and 0.24. When using
 0.23 I needed to use a similarly modified version of 6200ch to change
 channels. I removed this from mythtv-setup for 0.24.

 After the upgrade to 0.24 I was no longer able to switch to liveTV or
 record any programs. My STB has an LED display on the front panel which
 shows digit-by-digit when a number is pressed on the remote or sent to it
 via firewire. When I select liveTV in mythfrontend I see the 3 digits sent
 to the STB the same as in 0.23. I also see the OSD come up briefly and
 show "Signal 100% TLAM Lock", but before the playback can start (1-2
 seconds later) I see the 3 channel digits get sent to the STB again, then
 the frontend returns to the menu with an error. I have tried to change the
 tuner timeout in mythtv-setup to as high as 20000ms but it appears to make
 no difference.

 Steps to reproduce:
 1. With a Motorola DCX-3200-M STB apply the attached patches
 2. Build & install mythtv-0.24
 3. Run MythTV-setup to upgrade the database, remove the external channel
 4. Start mythbackend and mythfrontend upgrading the database as needed
 5. Attempt to watch live TV. Output as per attached logs.

 I can revert to 0.23 + 6200ch and things are working normally again.
