Hi People,

Looking for some advice, I have a Scientific Atlanta 4250 and a MCE (2 port blaster), a serial blaster and a firewire cable. I would like very much to get channel changing working on the Scientific Atlanta 4250.

My perfered method would be IR blasting (I under stand it much better, but am still having a hard time with this new box). I only have one Scientific Atlanta 4250 and I am just looking to see if anyone out there has it working and what settings they used to get it working. Perferably in the simpliest method.

Any help would be appriciated.

Thanks,

Paul

When I see your channel change script, it says 'REMOTE_NAME=Streamzap_PC_Remote'. That is probably the remote your using to control the mythbox, but it's looking for the remote name used to control the cable box. A quick peek in '/usr/MythVantage/templates/transmit/sciatl_exp2xxx_3xxx_4xxx/lircd.conf' shows that the remote name should be set to 'SAE8000'. Give that a try and see what happens.

Also, in case you weren't aware, if you look at the blaster through a digital camera or video camera it will pick up the ir signals as a flashing light so you can at least verify that your hardware is working. If that works but it doesn't change channels then it's probably sending the wrong codes.

Good luck.
