You don't need that patch unless you want to use the IR Blaster that 
comes with the PVR-150 and PVR-350 (does the PVR-350 come with one?).

The onboard encoder is actually a desirable item.  It takes the pressure 
away from the CPU. :)  The 350 might not be supported, but it should 
work since it was only just recently said to be "unsupported".  If you 
have one already, give it a whirl.  However, I wouldn't go out and buy 
one off the shelf.. if you are going to do that, go for the newer 150 or
