Nathan,

I understand your code needs to accommodate the 30/60 fps for NTSC cameras.
Do you have any idea how long it might take to incorporate that? We're 
eager to
have that capability. We'd also like to see this on MacOS. We can devote 
some
time to do this if you aren't able. Using your work in Windows would 
certainly
make this easier. Let us know what your plans are.

Thanks,

-gurcharan
