i am totally new to video conversion and i bought Ulead DVD Movie Factory as it seemed to fill my needs.I only have problems durin the conversion process to mpeg 2 to burn to dvd. The process seems to be done automatic by the program.but when i play the converted video before the burn process it plays perfect for about 50 to 60 minutes and then the soundtrack falls back 5 to 10 minutes and on one occassion there was no sound at all after 1 hr.Most of my project are films from the net and i don't have this problewm with every one. Has anyone any suggestions please
