HI - I love the software but I have a heap of trouble getting the Audio to Synch with the Videos I make.

Could it be the fact they are .AVI files done on a Digital camera?

I have tried several tools and techniques but I am still struggling.

Would appreciate any suggestions.

usually when I add the Clip and click the Play Clip button - the synch seems ok.

Once I drag the clip below to the editing area the synch go and I cannot get it back.

Yes, it is probably related to your clip format especially if you notice it after trimming some from the beginning. In that case, you need to transcode it to something like Lossless Matroska - available as a Transcode preset in v0.7.6.
