Hi playme123,
The default totem movie player may not play all movie formats. What format were you trying to play - e.g. .mpg, .wmv? Totem will not play either.
To get .mpg movies to play, it is likely that you will have to either download a binary version of mplayer for wubi, or download both codecs and gcc in order to compile mplayer for wubi in order to play .mpg movies.
I don't know much about wubi, but I have posted other message threads in this forum - see the one about mplayer posted by clenny for more information on building mplayer and getting gcc which is Ubuntu related.
Wubi is an installer for Ubuntu - i.e. not a Linux distro in and of itself, and is Windows based and the project is in beta test currently - which means use at your own risk usually because it is not yet supported.
I would not try the above unless you commit to an actual Linux distro installation in its own bootable partition - i.e. definitely not with Wubi.

P.S. The reason you were probably ignored on the Ubuntu forums is that the program runs in Windows and is not an actual Linux distro. See more info about Wubi
here.
