Audio and video does not synchronize at preview

Question:

When I previewed from the middle of the timeline, audio and video are not synchronized well.
If I played from the beginning of the timeline, it works OK.

It also works well when the video is created on PC and played.

Answer:

LoiLoScope series put priority on synchronizing editing and time, so there are some chances a part of a video is not displayed, so looks stopped. How it plays at preview highly depends on the system environment, and it often happens on avi videos.

All these happens only at preview so the resulting video on PC/DVD/BD runs as edited and should work fine.
