Loss of AV sync when editing recorded SD Digital

[lgare]

Gday,
I'n in Aus, using an AVerMedia card. I can record SD fine, and play it back in Windows MP fine.
But when I edit using Adobe Premiere 7.0 (Pro) the audio and video gets out of sync.
I think I need something to re-encode the mpeg. Any tips?

Thanks

UPDATE:
I now use a program called VideoReDo http://www.drdsystems.com/VideoReDo/index.htm to free my files from any glitches, and to edit to the start and finish frames.

I then use Premiere Pro, with a plugin from MainConcept http://www.mainconcept.com/mpeg_pro.shtml

One of the reasons I was getting errors was because:
"Although Premiere Pro will import MPEG-1 and MPEG-2 material, it does not offer native MPEG editing or smart MPEG rendering. This means that MPEG data needs to be converted to another format (such as DV) for editing, and each frame must be re-rendered even if no changes have been made. And if your target format is MPEG, you'll need to convert your finished project back to MPEG.

The MainConcept MPEG Pro plug-in eliminates these limitations and turns MPEG-1 and MPEG-2 editing into a productive, high-quality workflow."

Hope this helps someone!
