Just wanted to let you know, someone had developed an Android and Playbook application to use with the Patriot Box Office. It basically will build a playlist for you in a separate folder in your HDD section of your Browser on your PBO. That means you won't have to use your remote to scroll through a huge list of files.
I think due to limitations of the box it can't directly start playing it. Although if anyone figured that out I am sure the developer would love to hear how it could be done. Here is the link:
Works pretty good.
