Ok, one more update and please understand I have no idea what I'm doing:
I modified sa4250_ch_new.c and set up that section as follows:
#define SA4200HD_VENDOR_ID1 0x000014f8
#define SA4200HD_MODEL_ID1 0x00001072
#define SA4250HD_VENDOR_ID1 0x000022ce /* jerkychew's stb */
#define SA4250HD_MODEL_ID1 0x000010cc /* jerkychew's stb */
I then compiled it using sudo gcc -o sa4250_ch_new sa4250_ch_new.c -lrom1394
-lavc1394 -lraw1394 and moved it to /usr/local/bin
I cd'ed to that directory and ran the following, with the following result:
matt at mythdev:/usr/local/bin$ ./sa4250_ch_new -n 1 785
Changing channel 785
matt at mythdev:/usr/local/bin$ ./sa4250_ch_new -v -n 1 785
node 1: vendor_id = 0x000022ce model_id = 0x000010cc
Device acquired on node 1
Changing channel 785
AV/C Command: cmd0=0x00487ce7 cmd1=0x04031100 cmd2=0xff000000
But it still never changes. Still out of ideas. I downloaded Scott
Bickford's script and will try to compile that.
