I have loaded Knoppmyth r4v4.1 onto my systems and everything has appeared to load just fine. My problem is trying to change channels via my Hauppauge pvr350 remote. I can control all of my menus just fine using my Hauppauge remote but when I watch tv it will not change the channels. I need to use my RCA DRD435 remote pointed at the RCA box to change channels. Here is how I have things connected:

DirecTV--->RCA DRD435RH--(svideo)-->PVR350-->ati9000-->monitor
|
|--(serial cable)--->PC

I have searched the forums and I am a bit confused. I believe I need to find some perl script that controls my RCA box, put the script in /usr/local/bin/<changechannel.pl> and call it up via the setup screens, somewhere. Am I on the right track? Where do I find the scripts that control my particular DirecTV box? Any help would be appreciated.

I also have no sound but I will fight that battle next.
