My DH bought me a DVD/PVR when they first came out at a cost of nearly $800
The stupid thing only worked for 2 years and then packed it in. I was about to throw it out when DH said he thought he took out extended warranty. I had a look and it was covered for 4 years. It works perfectly now, but I wouldn't have paid to have it fixed because the technology is so much more advanced and cheaper now.
You should be able to record your shows onto a DVD. That's what I did with mine. Took hours to record something over to a DVD but it did it eventually!
