Sounds like you need to kick your attorney in the ass! This is not brain surgery!

Here is the DMCA Designated Agent for Multiply.com. Your attorney needs to send them a DMCA compliant take down notice for your films. If they do not respond, you send it again and again. Once you have legally put them on notice and they do not comply, they then become legally liable for the infringment. In other words you get to sue Multiply for the infringements! ;-)

Any decent attorney should be able to figure this out.
