I'm usning Vista Ultimate. I have used VOB2MPG to create a playable format for my xbox360 extenders for several movies. I now want to take that single mpg file and convert is back to a playable dvd file to burn to disc. Everytime i run nero vision to convert the mpg file to dvd file on my hard drive , nero vision crashes and the nero smartstart opens up. Sometimes it reboots my pc. I have tried this process on over 10 different files , about 50% of the way through the process the same thing happens. I have uninstalled with nero clean tool and reinstalled 3 times and problem still exists. I am usning nero 220.127.116.11 with nero vision 18.104.22.168 Any ideas on why this is crashing. I have also tried to rename the NEVideo.ax file, but that results in the files not even being able to be seen.
