Hi all: I installed the latest Imgburn. I first ran dvd shrink v3.2, I edited a one hour movie I had on a dvd that works fine but I wanted to remove some of the beginning and end of the movie. In Shrink I made an .iso file. I loaded it into Imgburn and burned a resultant dvd. I played the dvd on my TV set-top DVD player and it worked fine. BUT when I went to watch it on my Win7(64) computer my VLC Media player said it could not open the disc. I tried it on other programs I have on my computer and none could open the disc to play the dvd. I brought it to work and it opened fine on a Win7(64) and a XP machine. Does anyone know what could cause this? Thanking in advance.
