Multimedia Workouts

I was instructed a couple of years ago to get more exercise by my doctor. (You know, the high blood pressure, high cholestorol, excercise if you don't want to die sort of crap.) So we bought a treadmill and I get on a few times per week. It's a pretty decent NordicTrack unit. Working out is pretty boring when you're not doing anything and just looking at a beige wall.
I decided that I wanted to watch TV or videos while I exercised. I have a lot of music videos on the computer as well, so I was going to build a home workout entertainment centre.
I had an older 2 ghz computer with a DVD drive and bought a Hauppauge (I have no idea how to pronouce this.) WinTV PVR-150 tuner card from NCIX.com for about $39 on sale. I hooked it up to a nearby cable TV connection and mounted a 22 inch LCD monitor to the wall. I had first looked at MythTV which is an open source Ubuntu application which works like a PVR. I had tried for several weeks to get MythTV to run without much success even though there was quite a bit of support for it, so I fell back onto good old Windows XP.
The WinTV card came with tuner software to watch and record broadcasts. So I can watch TV, DVDs, video clips (AVI, Mpg, etc.), listen to MP3s and actually do work on the computer if I could figure out how to run and type at the same time.
It's been working pretty well and the time goes by a lot faster and it's almost fun to workout. (Just kidding. It still really sucks.)
