Avi made in VirtualDub unnaturally slow

[lcask]

I have a problem, using VirtualDub in making DivX I probably set up some parametre resulting in a strange manner - the output - .AVI - when playing is I guess twice slower than origin...

Any advice what to correct in VirtualDub (because I am sure here is a problem - AVI file coded in Nandub is OK) or better to reistall VirtualDub...

Thanx
