How are you guys actually using an
ovr file with tdecimate? I'd try everything to specify a dropped frame or pattern, and it seems to be of no effect. The frame that i've specified to drop would still be there.
I'd use tfm with tdecimate sorta like this
tfm(mode=4,pp=1,slow=2,flags=1,hint=true)
tdecimate(mode=1,expp=true,ovr="C:\Myovr.txt")
The "ovr" file would read something like this
