Hi, I Wonder if Anyone can help me,

I Im having a audio sync problem with sony vegas 8, I have convertered some music videos from vts files to avi files, the properties when convertered are as follows:

Audio: 01:12:41.378, 128 kBit/s, 44,100 Hz, Stereo, Lame MP3
Video: 01:12:31.600, 25.000 fps, 720x576x32, Xvid MPEG-4 Codec

If I play the avi file with a normal windows media player or K lite player it plays in sync.

If I play it in sony vegas 8 it plays out of sync I have tried all the different fps settings on the sony vegas preview screen but it still plays out of sync.
If I put the playback rate to 1.003 it is near enough in sync but not perfect.

I need to find the correct settings for playback so I can use the same settings for rendering.
This is an avi file that I want to take certain music video's out of.

Any help please
