I have just purchased Pinnacles Dazzle Fusion with Stuidio 8. When recording VHS tapes to hard drive the sound is out of sync with video so I can't burn to DVD. I have C+D drives, Studio 8 on C and capture to D. I'm using a scart to video out - to Dazzle Box. Any ideas please.

Sync Problems can be caused from a Number of Different things....

If you drop frames while Captureing that will cause sync problems...
If the Video and Audio Clocks are different (Which they allmost allways are) then you will get the Audio and Video slowly drifting appart.....

Most Pinnacle Products in there Consumer Product Line up suck, the Only good Stuff that Pinnacle Makes are there Professinal Broadcast eqipment and Professinal Video editing Software/Equipment and they Don"t make a single Good USB device......

So I guess what your saying is there is no way to correct this problem and I just wasted £50.

Did you try demuxing the audio and video then remux to see if corrections can be made at that time?

Don't mean to sound stupid but what is demuxing and remuxing? How do you go about it?

I was just asking if your Pinnacle s/w has a way to separate the audio from the video into two different files. Then put them back together.
Though like minion says, sync issues can be caused by a number of things at a hardware level. Try to determine if your computer is allocating most of it's resources to the capture process. This may help eliminate sync problems. If that area seems ok then I would look into the things you might be able to do with your software. Maybe this is commom among Dazzle users, I don't know, but perhaps it can be fixed by stripping out the audio and applying a change/fix to it then putting it back into the video stream.
I'm no expert, just thought I'd throw out some suggestions of where you might want to turn.

You should look for a tool called "PVAStrumento" it is For Fixing Time code errors in Captured Transport Streams like when Captureing from Satalite...

This is supposed to Fix Sync problems with Satalite Captures....

You can download it on this Page:
