Streaming problems on MR3020

I set up my Piratebox using a MR3020. I am able to access the main page, use comments, upload, and download files. I seem to be having trouble streaming media. I downloaded the ACE player on my iphone and selected my Piratebox as the media server. I was unable to find any files that were on my piratebox.

I activated and enabled the UPnP server on the box before I tried this.

Any ideas?

Thank you!
