SW4 Iso has audio delay, why?

Playing an Iso Image of the SW4 DVD on my notebook, I noticed an audio delay of about 2 seconds. The ISO was done with decryptor 3510. How does that audio delay come about? Thanks for help or link!

Well, it is a problem with the software player. On another computer, the very same iso plays fine on the same player. Go figure that...
