I just upgraded from generic +r 4x to plextor +- 8x dvd writer. I used xcopy platinum with +r 4x and it worked great with finished product playing back on my dvd player that is hooked to TV. I swapped out the 4x with the 8x and couldn't get copy to play on dvd player. Plextor tech said it was because the xcopy doesn't support 8x burning speed. They said to rip with xcopy, then minimize program because closing program would delete the temporary movie rip file. then use nero or roxio to burn to dvd. Works great but now it plays on one dvd player and not others that it used to with straight xcopy procedure. Does anyone know if Roxio dvd creator conflicts with dvd xcopy platinum?
