Well I have got this error on a few movies that I have been trying to encode, I am not sure what they were but this one is divx 3.
At a certain point in the encode I will get the error "Illegal floating decimal point calculation" and the encode will stop (in this case that was 5 hours in). and as detailed as that error message is I am not able to find out what causes it.
If it is just shit source, then I guess that is fine, although frustrating. But if there is something adjustable in the prgram to get around this than that would be better.
