MPEG4 H264\AVC Problems converting mpeg4 to dvd

The only program that manages to attempt to convert this MPEG4 type is VSO DivxtoDVD. I usualy manage to get 50fps when converting avi to dvd. But ive tried using NERO Re-Ecode and VSO DivxtoDVD, VSO slows down to about 3fps and NERO re-encode just shuts down. I can play the MPEG 4 file ok, but when i look at the converted file using VSO DIVXTODVD the sound seems to be playing in slow mo, any ideas how i can convert MPEG4 to dvd with success. This is the codec information i got from the MPEG 4 file H264\AVC
