or TV tuner card is all you need for your PC. It'll come with the software you need. Do a Google search on TV tuner cards.
I have a USB unit that makes my PC a TIVO, and included the software to burn DVDs.
Then again, maybe you really want a new PC??
What I'm hoping to do is record tv and burn dvds from a new computer (children's shows for my kids to watch in the minivan, entire seasons of shows, etc.). I'm looking for a computer with this capability - right now, it looks like there is an HP 7060 and a Gateway, both around $1000 at Bestbuy. It seems like a lot of people on here don't like the configuration of the HP. Anyone know how it will work for what I plan on doing? Other than what I just listed, I'll be making dvds from a minidv camera, downloadinging and photoshopping photos, and the internet. Not much gaming (xbox and soon xbox 360 for that).
Suggestions? HP or Gateway or other? Bestbuy? Looking to spend about $1000.
