First of all, my sincere apologies if this is a repost or if I'm posting my problem in the wrong section.
I have a problem in PowerDirector, in which my MP4 videos recorded by a Sanyo Xacti VPC-HD1 have a audio-video delay; in other words, the audio is not in sync with the video. Although, in some of the previews, like when I'm choosing the media I want to import to the workspace, it has no sync problems at all. But when I'm working with them in the workspace, it has all those sync problems, a few seconds of delay.
Can anyone lend me some help in this situation?
A 'many thanks' in advance. [[[[]]]]
P.S.: It's probably good to inform that viewing these MP4 videos on some players like WMP or MPC, these sync problems also appear. I have to use VLC Media Player to watch them without any issues.
