hey i got the OME of roxio creator & MyDVD 9.0 with a notebook which contained windows vista
i now have downgraded to windows xp pro and when i go to install
it says that the operating system does not support it
any ideas?
i contacted the place where i bought the notebook from and they said the cd i have supports all OS's
so i am unsure of what to do
can anybody help?

It's possible thta th eplace you bought it from isn't right.If you have an OEM version of the sofware there's a chance that it has been modified by the mfg of the computer to cause this.Try contacting them.
