I used to be able to burn video DVDs from Media Center but now I can't. I
can still burn data DVDs but every time I try to burn one in video format I
get the 'Burn Failure' message as well as a popup in Vista telling me that
SBEServer was stopped by DEP.

Since this used to work, I guessing that some setting or component was
changed but I don't know what it was. Is there a way to remove and reinstall
the DVD burning components of Vista Media Center?
