I gave up on Hauppauge fixing the Windows 8 Media center issue with Colossus. If you are having this issue, you can look into NextPVR, which is available free or for a donation. It's a bit quirky to get setup, but so far it's worked very well for me using Colossus. It has a guide similar to WMC, and recording is just as easy. It stores its recorded files as .TS files (same as WinTV 7), not the Microsoft specific ones recorded by WMC. If anyone is interested, I have a "guide" on setting it up for Colossus. I will post that here on request.
