Windows DVD played on a Mac

[#1]

I have some video DVDs which I copied using DVD Decrypter software on a Windows XP system.  They all run perfectly on the Windows XP system (video_ts format).  Does anyone know whether these DVDs will also run on a Mac or do they have to be reburnt into some sort of Mac format ?  I know absolutely nothing about Macs and their compatability with Windows ?

The video_ts format will be fine for Macs.

Thanks very much for the information.
