I'm working on a music video for a contest...the submission deadline is closely approaching and fist i thought my video problem was in the encoding...but now i've narrowed the problem down to DVD_LaB_Pro_2. I have a music video and have made 3 types of audio...a pcm, dolby 5.1, and DTS. whenever I burn a simple movie( my video with just the pcm(wav) or dolby AC3(2-channel) it plays fine. But, when I try to author it with Menu + audio selection menu( with all three audio streams) the resulting DVD disc the video hangs up(pauses for brief 1/4 second intervels)...real bad...during playback it's ruining the video.....but still altogether the menus work fine and the whole vob is only 600mb. Any ideals what's causing this?
