From what I've read, only game consoles and maybe DirecTV receivers output HDMI without HDCP. So, forget that. If you have component outputs, you can use those.
As far as Windows Media Center goes, I can only give you my own experiences. I'm using Win7 x64, but I have two Hauppauge 2250 tuners. Windows Media Center will not see the 1512 and there are no WMC drivers available. So, you're stuck with WinTV7. YMMV, but I've not been able to get WinTV7 to install properly and co-exist with WMC. WinTV7 starts with a ton of errors. "Failed to attach TS slip filter" and "Failed to attach TS File Reader" errors to be specific. It will eventually start and run, but it's buggy as hell. Took a registry hack to get the IR blaster to work. If WinTV and Windows Media Center have scheduled recordings that overlap, WinTV7 fails.
If you have any other Hauppauge devices installed, it will wreck the 1512's installation. The install program assumes the 1512 is the only thing you have. Customer support confirms they never counted on someone having this box AND a tuner card.
One bug that seems to be an issue for everyone is recording via component video with optical audio. There are beta drivers that'll fix that for most, but it's still gonna take some work.
All that said, I still have the 1512. In addition to WInTV7, the box comes with an old Arcsoft capture program. That's what I've been using the most.
If all you're gonna do is manually capture stuff, you'll be fine. Otherwise, get the 1212 or wait until the 1512 is ready for prime time.
