When importing a video (mpeg-1) clip into Ulead Media Studio 6.5 / Veditor, the picture and audio are normal. After placing in / out marks, and applying , then draqgging to the timeline and rendering for preview or export, I lose all audio/video sync. This can vary from the a few frames, to 30 or more out of sync.

The filespec in Ulead is Video CD / NTSC (White book compatible). However, altering this spec has had no effect on the sync issue. Has anyone encountered an error like this? Please help.
