I now can watch TV with coax (I need to buy an S-video cable). But can 
only use the STB remote. Mythtv cannot still control using a remote.

I am not too sure if I have an IR blaster or an IR reciever

I purchased the PVR150 in June 2006 and back then the remote worked with 
Mythtv (no STB, just wall to pvr150 back then)


The cable that attaches to the IR port on the back of the card has 2 
cables ( but none of them light up, no LEDs). The remote I have is grey and

and I bought this very recently

http://www.anywareus.com/products/misc/gpir01bk.html (I read that this 
remote works out-of-box in linux)

If I don't have an IR blaster, I will get one hook it up to the stb box. 
And what is channel change script? How do I set it up? Do I need to do 
anything else with lirc? Does the latest kernel (F11, have drivers?
