can any body help?

recently I just buy "Shrek" & "American beauty", both of them released by Dreamworks. All feature inside, seem to work well but I can't play the movie(the main reason why I buy) on my PC.
If I compare to my old dvd the difference is: there are no file under VIDEO_TS folder.
I've try to play it by WINDVD, PowerDVD, etc, but still can't work.
is there something wrong with the DVD or my PC?
My friend try to play it on his DVD player and it work, he can see the movie...
can anybody help me with this, at least I need an explenation...
is there such dvd that can be played on dvd player but can not in PC?
For information I use Toshiba SD-M1402 Drive, and Athlon 700MHz.

thanks

" there are no file under VIDEO_TS folder. "

This is not a legitimate commercial DVD - it's a pirate version.

Did you buy it from somewhere in Asia?
