Video TS and Surround sound?

Hi all,

I am possibly missing something here but is it possible to get surround sound from a VIDEO TS folder? I am using ‘fairmount’ on my Mac to copy the VIDEO TS folder off a DVD and then putting it onto my USB hard drive. All works fine except for surround sound? Am I missing something? Is there an easy to copy a DVD and get surround sound without having to rip and convert the film which takes ages!

Cheers all.
