This months Mikrobitti (Finnish tech mag) has a roundup of a few PVR softwares, MP, GB-PVR, MyTheatre and DVBviewer.
Basically said that MP resembles MCE interface, free so great for testing and still offers a good match for the comercial offerings.
Lots of addons that improve the software, and the TV part is just a small part of the software. etc etc.
A good choice if you use it for other things, not just for TV.
Pluses - Free and open source.
Minuses - Teletext Subtitle support -
