I don’t know how to say this any clearer. MCE Buddy Rocks!. It is free, but they request a donation. I haven’t seen any nag-ware.
If you run Windows Media Center 7 and want to do anything with the TV tuner recorded files, check out MCEBuddy. It does the simple stuff by default. I suppose it will work with older versions of media center too, but cannot confirm that. What is the simple stuff?
