Everything _appears_ to be working but the box just isn't changing channels.
I'm able to plug a GUID from dmesg | grep 1394 into sa4250_ch_ guid like so,
matt at mythdev:~$ sa4250_ch_guid 00110666000000b8 56
Changing channel 56
But the channel never changes. If I run the non GUID version verbosely I
matt at mythdev:~$ sa4250_ch_new -v 56
node 0: vendor_id = 0x00001106 model_id = 0x00000000
Device acquired on node 0
Changing channel 56
AV/C Command: cmd0=0x00487ce7 cmd1=0x04003800 cmd2=0xff000000
Again, with the channel never changing. I've tried powering everything down,
moving the cable to another firewire port and powering them back on (STB
first), with no result. Any ideas what to try next?
