AVI File - Audio / Video out of sync

Hi,

I've been looking on forums everywhere on the internet for an answer to the issue I've been having ever since I started using Vegas 5. When I record something from the Video In on my ATI AIW 9600, it records fine, everything is in sync when viewed in Windows Media or the software that came with my video card. When I preview the same clip in Vegas, the video is ahead of the audio by about a second or so. I have read that it might have been because of an overclocked CPU, too many programs running in the background or that the onboard sound is hogging processing time. So because I'm not overclocking or have many programs open at the same time, I went out and got a soundcard. I purchased a Turtle Beach Santa Cruz board and installed it... The same thing happened! When I recorded and played it back in Windows Media everything was fine, and when I played it in Vegas, once again the audio / video were out of sync. I realize there are programs such as VirtualDub that will help correct this issue, but doing that adds another step in the editing process that's rather inconvenient.

Does anybody know of a fix for this issue? I really don't want to use another program because I was just starting to get good at Vegas...

Thanks for any help / advice in advance!

I'm guessing;

Video is usually a sample rate of 48 kHz and Vegas' project properties is 44.1 by default.

Check the sample rate of the video's audio stream and set Vegas' project properties appropriately.

Mmm no... I tried that and it still doesn't play the way it's supposed to... :(

I have played around with almost every setting today and nothing fixes this... I've fooled around with sampling rates, compression, etc... Oddly enough when I record to MPEG the issue doesn't exist. But I really don't want to record to MPEG because the finished product is going to be WMV... Compressing an already compressed file isn't the best way to do things I think... Not only that but Vegas seems to work a little more sluggish when working with MPEG files. I have an AMD Barton 2500, 512 MB Ram, one 80 Gig HD, and a 20 Gig HD, and I have tried recording to both drives (individually) also, still no resolution. I'm running out of ideas... Any more gurus have any ideas?
