I went to Best Buy today and asked them if I could use Windows Media Center's Web Guide with a Tv tuner to watch Michigan games, which would pretty much be making my pc a dvr. I figured this is a much cheaper alternative to the slingbox. Has anyone used a tv tuner or done this before? Was it difficult? The guy at GeekSquad said he didn't know how to do it and that it would take some time to figure out how to set it up, but looking online I found this:http://www.microsoft.com/windows/windows-media-center/learn-more/record-tv/default.aspx , and it doesn't seem too difficult.
