[mythtv-users] External channel change program for Scientific Atlanta 4240HDC?

[Keith Pyle]

Does anyone have a working program for changing the channel on a
Scientific Atlanta 4240HDC via Firewire?  The usual searches turned up
nothing except some discussion of problems 2-3 years ago where the
sa4250_ch program reported success but did not change the channel.  That
is the behavior I see now, even after modifying 4250_ch.c to check the
return value of the command function call (i.e., the command function
avc1394_transaction_block returns a non-NULL value which is documented
as a successful command).

For now, I'm just trying to get channel changing via Firewire through a
standalone program instead of using lirc - not trying to capture in Myth
over Firewire.

Thanks.
