I have a DVD Recorder with the HDD. I have never had a problem with it and I run it just about 24/7. I think it is 3 1/2 years old.
As ResplendentRegina said, that he does not know if they make them anymore. I know Panasonic stopped making them. I was thinking about getting 1 with a larger HDD and the said they do not make them anymore.
If you got DirecTV, you may want to ask them what happens after they have to change over and get rid of the rabbit ears

I saw (I think on FoxNews) that to be able to watch DirecTV, you will need thier boxes to get the channels. It seems like they make upgrades to my DVR 1 or 2 times a month
As far as hooking up to your PC, I would not know about that, do to the upgrades DirecTV makes.
