I think your best bet would be to get a DVD recorder.
Another way is to get a video capture card for your PC. You can get one that will record HD through the component cables but it isn't cheap.
There is also a program to transfer programs from your PVR to a computer.
Here's a thread that discusses the solutions.

If you can live without the PIP and the second TV option, I'd opt for the 9241 as you can use an external Hard Drive, so you won't run into this problem again or wait till later this year for new receiver to come.
