What kind of footage?
Are you trying to sync up a camera and some sort of audio recorder? If so what are the setting on your audio recorder?
Welcome to the forum.
Can you give us details about the files, and as Pebalsmo asks, the equipment used. The more details, the better.
Apologies, I should have explained this better, I filmed a one hour talk using a Sony v1e on HDV setting. I then digitised the footage using the correct presets on premiere. On listening to the clip from the timeline the lip sync begins to run out - after 45minutes it is 11frames between picture/audio. I played the captured file in windows media player and its okay. I am using a HP z400 with a Nvidia Quadro 4000 graphics card.
I have used cs3/4 in the past and never had any problems? any suggestions thanks Jim

You mention HDV... which I understand to mean you are using a TAPE camcorder, and you then use Firewire to bring the file into PPro... correct?
Do you have a red line on your timeline?

Report back with the codec details of your file, use the programs below

Once you know exactly what it is you are editing, report back with that information... and your project setting, and if there is a red line above the video in the timeline, which indicates a mismatch between video and project

Not really a fix but try capturing in small chunks instead of the whole hour.
If it stays in sync then you can at least work on the project while someone figures out why its not syncing up the audio.
Just rewind the tape a little each time so there is enough overlap to bring in all the pieces and put them back together.
