First im hearing about re-editing of clips during render.
Open up your Vegas 9 project files in Vegas 10, Make sure
everything is nicely lined up and accurate throughout the
timeline, Then save your project as a different name.
Close Vegas, then re-open it. Now open the saved project
on the timeline and do your render….You should have no
problem there.
