you need to define Forder...
try it with just "order=1"
[edit]
oh, if you're using DV as a source, you should go "order=0" i think.
or use this to determine it:
Code:
#assumetff()
assumebff()
order = (last.getparity==true)? 1 : 0
tdeint(order=order)
unless you're making a customized function, there's probably not much need for all that, and a simple 1 or 0 would suffice.
