Along the same vein as our previous news story, we have a user's review of MythTV vs Vista. I just finished reading it and it is a good writeup that has valueable info in it if you are on the fence about which OS to go with in the HTPC world.

Now, here's MY killer issue with this install… ready? Drivers. Yep, I said drivers as in: problem in Windows despite being rock solid in Linux. Surpirised? Well me too but I shouldn't be because it's conventional wisdom that Windows stays in beta until at least 2 years after major version launch. So anyway, my video cap card doesn't fully work! Only one of two tuners is recognized. I've tried all the standard tricks and latest driver releases, with no success yet. Even my long distance call to Hauppauge was fruitless and I suspect that I'll be waiting for some system update or new driver release before I can watch one show while recording another. Or maybe I will fix it before then, but certainly not without a little googling, FAQ searching, or phone queueing.
