ok ok ok I have found an answer to the problem…….
If you bring up your log and transfer window and goto preferences on the transfer window and uncheck
“remove Advanced pulldown and dup frames” the issue will disappear….
it seems it is a frame rate issue not being accurate for both video and audio,
as to why this corrects the problem is anyones guess…anyone care to hazzard a guess?
hopes this puts a smile onya faces..
:o)
