Studio 8 is a great tool, but it can be a pain in the **** sometimes. Please can you tell me how far you get with the burning of the CD, and what burning software you have on your PC as well as the Studio software.
IE A) Do you have Nero or something like that ?
B) Do you actually get as far as Studio stating that the burn process is complete, or does it just start to burn then fail ?
Have you tried setting the Make movie to just burn to the hard drive then make the disc later ?
I Found this resolved a lot of DVD burning problems.
Or you could try putting the finished article back to tape, then re loading the finished edited footage back into Studio then make a VCD. ( A pain I know but that way Studio only has to burn the disc rather then render all of the edits etc )
