Well, RealPlayer is available for Linux
. I'm not sure what the difference is between that and RealOne.
I'm not at all sure about the error you're getting with Office. I've heard it's pretty hard to get MS Office to work in Wine. There is Crossover Office
which is designed to get MS Office running in Linux, but unless you desperately and specifically need Microsoft Office, I'd suggest using a Linux-native office suite like OpenOffice
(which is almost completely compatible with MS Office), KOffice, etc.
It may also depend greatly on what version of Wine you are using. Do you have any idea what version it is? (type 'wine --version' in a terminal window to find out.) More recent versions are probably likely to work better.
