I have problems frameserving to TMPG using VirtualDub, when I open the file in TMPG it looks fine, but when I try to encode it it gives an error message "The error occurred when ACM was initialized." and then usually (but not allways) gives another message "Illegal floating decimal point calculation order." The problem is probably with the sound becuase when I select 'No Audio' in VirtualDub and then frameserving it there's no error and the encoding is excellent. I don't know why this is happening but I can tell you it used to work for me in the past, so please help me.
