Hi Ralphtalk!!! They really have a serious problem with the Media Center after SP1. All the forums are buzzing bad---- NO UPDATES FROM MICROSOFT, MEDIA CENTER SP1. People are reporting - will not play dvr-ms or stream T.V. Some are reporting endless rebooting. I can't speak about the T.V. aspect because I don't use, but I did lose my speakers following installation for Media Center Windows Vista (JAN,FEB) I went back to factory settings and it seems to be working alright now. I'm having some trouble with Rhapsody, it may have hurt the files. There has been complaints about that also.
