I'm discussing this issue with Jean-Pierre Lemoine, via email, and he 
says that AVS is basically built around the idea of using integer frame 
rate values.

He said he may release the next version with the ability to accept 
fractional frame rates, but in that case A/V sync is not guaranteed.

But all hope is not lost. There are some frame interpolators out there 
that might just be good enough to adjust from 30 to 30/1.001 fps and not 
destroy the image quality. I need to do some experiments.
