Well, earlier today I decided to upgrade my ATI MMC. Fortunately for me it decided to take away my television privileges.
So I needed a good WDM capture (with internal audio capture) software and I went through several (InterVideo WinDVR, DScaler, iuVCR) before I found K!TV.

Excellent software, very good picture and good audio sync. A little slow on the channel search but no complaints so far.
