can I update my dvd x copy xpress program?

U will have to check with the authors website. Usually updates can be downloaded direct from the website, just depends on their policies.

thanks...How do I find out where the authors website is?

No, they were forced out of business, because of the Digital Millennium Copyright Act - Wikipedia, the free encyclopedia
Ther are some other programs out there though.
FYI - If you are in the U.S. while it is not illeagal to make a copy of a dvd it is illeagal to break the copy protection. (required to make a copy of most commercial dvd's)
Do a search for DVD decrypter and DVD shrink. They will do the same job as DVD X copy. But be aware the info stated above may apply.

On DvdShrink and DVD Decryptor. There is a nice useful tool called RipIt4Me, which requires both the above programs. Makes it very easy
