Channel Change control for SA4200 via firewire.
The SA3250 channel change utility does not work for the SA4200 box. It
seems to have a different command structure. After putzing around with a
bunch of bit settings, I think I found one that works. (Basically
SA4200's vendor id is 0x14f8 and model_id is 0x1072 and you send the
same command, except cmd[1] is simply CTL_CMD1 | (chn << 8);
sa4200ch.c is attached.
I don't think the key_release command in sa3250 was being sent right,
I've found that simply sending it in one transaction works better.
I don't know howto make this an internal thing instead of an external
tool, if someone could point me in the right direction I'll create a patch
for that as well.
