I was browsing the net and came accross an open source media center alternative for windows. It seems to have a lot of features such as tv broadcasting of multiple channels and has some sort of support for encrypted channels. It does have a few bugs from what i read but it looks like it has a lot of potential. Check it out and tell me what you think. It looks very interesting. You can find it at
