When ever I send a attachment, ie .WMV file, using outlook express, it is broken down into multi text files.
Any ideas why this is happening?

I found out what was causing the prooblem. The setting for the breaking up of large attachments was set at 25 KB. I bumped it up to 5000 KB and it works fine now.

TOOLS, ACCOUNTS, MAIL, PROPERTIES,ADVANCED, SENDING

Thanks for the update and the info!
