24f workflow///render issue//audio not sync'd
 

Shot a music video with xha1(24f SD). Captured video into Vegas Pro 7. Matched properties of captured footage. Edited video clips and matched to sound track. Here's my problem:

When I render out to mp4 or mov 24fps it appears that the audio slowly falls behind. By the end of the 3 min clip, it is off by quite a bit. When I render out to mpg2/ac3 and view it in dvda, all is good. I even tried rendering to mpg2/ac3 and then bringing it back into the timeline and try rendering that out to mp4 or mov with the same results. I was successful if I rendered out to .wmv.

Is there a solution to this problem?

Is rendering out in 24fps causing my problem?

Help please. I feel I am overlooking something simple.

Thanks in advance.

PROBLEM SOLVED:

When rendering 24p project, I had to change the "frame rate" in the dialouge box. See link. http://eugenia.gnomefiles.org/images/mainconcept.png
