Personally, I would recommend Windows 7 Home Premium as an OTA TV solution. If you don't have a license, they can be purchased for ~$100. If you use GB-PVR or MediaPortal, you may need an annual guide listings subscription. There are some free Zap2it scrapers but they are a little tricky to configure.
I tried both those products when I assembled my HTPC a few years ago. Both were a pain in the ass to configure and MediaPortal was buggy as hell when recording TV or browsing the guide while watching live TV. After a month of playing around with those 2 products (I couldn't try Myth because my ATI 650 PCIe tuner was unsupported) I configured Vista as my main TV solution. I have since upgraded to Windows 7 and for TV, I love it! That being said, I do use XBMC for everything else (I can swap between the two programs using my remote).
Sadly, there is no killer Media Center/TV combo app out there YET. Some are better at one thing or another (IMO nothing beats XBMC for media). W7MC is rock solid and reliable for TV but needs plugins to manage media better (see 'Media Browser').
