I'm sure there are some knowledgeable and helpful tech savvy folks that frequent this area. Any help that you could provide would be greatly appreciated.

Here's the situation.

I have a new place, and am currently using Comcast for TV/internet. Right now all i have from them is basically an HD cable box and that's it for my main TV.

My fiancee and I keep up with 4-5 shows, and most are available on XFINITY's on demand service, which is nice, and lets us catch up when we miss stuff.

But not all of them are.

What options do I have for recording live TV so I can re-watch shows later?

I would prefer some kind of DVR with a recordable/rewritable hard drive. Do such things exist anymore? My parents had one several years ago, but I thought they discontinued making them.

I think I would prefer to buy one up front rather than subscribe to comcast for 10 bucks or w/e a month and pay hundreds of dollars over the course of a few years.

Any recommended brands/models?

Thanks all!
