[mythtv-users] Digital cable and two tuner cards

[Khanh Tran]

You need to set each tuner with a different channel change script.
change-channel-lirc.sh is provided in a contrib sub directory in the
source I think.  Just copy it to a second instace (like
change-channel-lirc2.sh) and then edit each with a different
REMOTE_NAME= variable set at the top.   Then your lircd.conf will need
to have the remote code for the cable box and match the name of the
variable.

Actually tin-foil works wonders ... :)

But the question is,  how can you tell PVR card #1 to record one channel
and PVR card #2 to record the other channel.

(Where in Canada can I get the IR Blaster)?????

How about taping the second IR blaster to the face of the second cable
box?
Do it in such a way as to:

1. mask the IR signal from cable box #1
2. mash the IR receiver of cable box #2 so it only sees the IR blaster
taped to its' face.
