Apparently you are referring to Photo Story 2?
Movie Maker is included with Windows XP
and is not related to MS Digital Image Suite.
Photo Story 2 and Photo Story 3 can both
run separately on the same computer. The
programs are not exactly the same and PS3
cannot create a VCD without a a special
plug-in from Sonic that costs $19.95.

As far as I know, the current version of
Windows Media Player is 10.00.00.3646.
Personally, I think it's wise to stay up to date
at the Windows Update site for security
reasons.
If you're referring to RealPlayer 10.5...that's
a completely different (non-Microsoft) program.
