as the title says guys , why am i getting the devide by zero error when i load an Mpeg 4 avi into tmpgenc 3 express, double checked the codecs installed and all seems well , play back is fine in seperate software players

i get the error when trying to play the file in express or when i try to encode it

i guess its a codec prob , but how can i sort the prob if my codecs look ok and installed properly ?

any advice guys please

actually i just tried loading it into vdub and i got the error msg about improper vbr and re-writing the header , i never know quite what to do with this , i always flounder a bit on that
