Thanks for all the help, it looks like majoridiot is the go-to guy for
channel changing on this box. I downloaded and compiled his script, however
I'm still running into the same issue as stated above - it shows 2 devices
on my firewire bus and I don't know which is the STB:

/sa4250_ch -v
node 0: vendor_id = 0x00001106 model_id = 0x00000000
node 1: vendor_id = 0x000022ce model_id = 0x000010cc
Could not find SA42XXHD on the 1394 bus!

If I dmesg | grep 1394 I get:
matt at mythdev:~$ dmesg | grep 1394

Thoughts on how to proceed?
