The theater in BearShare is actually an embedded window on the Window Media
Player already on your computer. I find that the best approach is to disable
that theater feature and set BearShare to use an external player for previews.

Here's how to do it:

• In BearShare, go to the View menu, then to Enable Views, and turn off the Theater.
• go to Setup menu, pick Options and set "Preview/play in Theater" to Never.
• Download and install Media Player Classic.

This player is much better at previewing incomplete files.

You may as well reinstall Pro and stick with it. We can also help you strengthen
it even further against spam and porn if you like.
