I have an ac-3 file and an mpeg-2 created in vegas 7. They come in to dvd-a ok, but when the disc completes it won't play properly. When I look at the drive of the dvd writer/player that I created it on it sees the final disc as a cd instead of dvd. I can see that the disc has been written to. When I tried to play it in another desktop computer dvd player, it won't play and all other dvd's I have created do. It does play in a third desktop I tried and a laptop, and it does play in 2 other regular DVD players. Haven't had this problem before, has always worked in the past. I thought it might be the DVD writer but two dvd players not opening it? Any ideas? Thanks.
p.s. It seems that if I do a single movie it will be ok, but when I try to do a menu based movie so I can add a start page, the dvd drive won't play it and it shows the drive as having a cd in it ready to write to it.
