I have a sync problem when editing (Pinnacle 12) the original soundtrack (and video) from the HDV tape and the ADDED audio track (music).

I can set the added audio (ripped in MP3 format from CD) to start at the exact right moment. After about one minute the added audio is about 1 sec out of sync. Its like the "pitch" is out and the added audio is a bit faster than the original sound!

The video is a WORK OUT instruction and its very disturbing when the added music get out of the instructors pace.

I can not use the original audio as it is from the camera microphone and is not a good quality sound. I want to MUTE the original mic sound and only use the added music track.

I have tried mp3, mp4, vma & wav format. All give the same problem. I have used different CDs and different "ripper" SW.

I use Pinnacle 12 Ultimate and Sony HDV camera.

Is this a known Pinnacle problem, or any other hints??

Thankful for any ideas how to solve this!
