Your posting doesn't work either.... !
What problem are you experiencing? From just the subject line I have no
idea what hardware you have on your PC and what software you have installed.
BUT:
To be able to watch a DVD on your PC you MUST have a DVD ROM drive or a DVD
burner drive....
AND
DVD decoding software, such as PowerDVD or WinDVD installed and with any
updates from the requisite manufacturer's websites.
