The problem with xbmc is that it doesn’t actually record tv shows itself. It’s very nice, it does many things, but doesn’t do that. Like I previously stated, I use win7 (median center works as a terrific DVR). However, you can save the $100+ if you go with linux and a MythTV install. It’s a customized version of linux. I found this wiki.

That shows all the tv tuner cards that work with it. Personally I use the tuner card for free tv alongside netflix and huluplus. That is pretty much the standard formula for ditching cable/dish. All you need is a custom built computer and $16 per month for netflix/hulu. There is a learning curve to figure out how to install and then work your new creation. So in that sense, your box is easier.
The thing is that for around twice the money, you could build yourself a similar machine that will also record tv shows automatically for you. You need to spend the time to actually build the machine and install the necessary software: The OS, TV tuner card software, xbmc and so on. Of course if the new system saves you $50 a month, that is time well spent imho.
And once you have the new system going you can do other fun stuff. Like put in a ton of photos and have a nice old fashioned slideshow to bore the pants outta all of your family and friends. :P
I mean to impress of course ;)
Have a nice day.
Heck, no one ever made money writing a bunch of checks. ☺
