After using Virtual Dub to save my 2 pass divx...I set dvtool to 1395 so it'd fit on 2x700mb cds. Then when I set virtual dub to encode with divx 4.11 I end up with the 2 files..the first pass and the second pass. The first pass is 1.2gb and the second pass is 2.2gb. I can not open the first pass. I can watch the second pass but if I move the navigation bar anywhere it will desync the sound. Am I supposed to do something else with the 2 files?
