No, there\'s no way to do that unfortunately. Closest thing you can do, is hook it to a tv tuner type card and record it to your pc.
Some people seem to let a hard drive fill up with a bunch of episodes (say all of x-files or whatever), then pop that drive out and keep it for a rainy day. Kinda expensive, then again you can get a 40gig drive for $100 now. Not too bad.
