Nerovision and A/V Sync Errors after Burn

I captured an mpeg2 file from my playstation via SVideo and my ATI card. The mpeg plays fine. I then burned to DVD with Nerovision with Chapters. Now the first 2 chapters play fine. Then the next 2 chapters have huge audio displacement problems. The next chapter plays fine. Then another chapter has audio problems and the last plays fine. Has anyone encountered this before and were you able to solve it?
