Alex, I use the sony.pl to control my external directv box. its an older RCA model. I had many of the same issues. of note, I'm using the sony.pl file to control my RCA! do some reserach and make sure that is the script for your model, or experiment with the ones you find. I have lots if you need them, just email and I'll send them over.
David has some good points. the best way to trouble shoot is to be root and try the script from the command line. do something like sony.pl 200 does it change to channel 200? I had to chmod 777 /dev/ttyS0 to get it to work. also, edit (vi) the script and make sure it calls the ttys0 port. some call other ports. if all else fails in linux and you suspect your cable (did it ever work?) then there is a window program that you can use to change channels from a windows box (have to google it, forget name. ) that works very well and can tell you if the basics are in place. _______________________________________________ mythtv-users mailing list mythtv-users@mythtv.org http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
