I have become a HDHomeRun Fan! This nifty little device adds dual HD-Tuner to your existing PC. Since it connects to your PC via network, you dont have to bother about lack of availability of PCI slots.

HDHomeRun is the first QAM tuner available on windows platform which integrates with MCE. I have been using Dvico FusionHDTV card for tuning OTA HD channels, but the drawback with that setup was ugly antenna in my living room. With HDHomeRun I have finally been able to get rid of indoor antenna, and dual tuner capability allows me to simultaneously record both Leno and Letterman in full HD glory :)

The integration of HDHomeRun with Windows MCE is quite straightforward and I strongly recommend this tuner to anyone looking for HDTV capability in his HTPC
