Add an item (YouTube Bulk Player Mate) to the default context menu of IE. It detects the YouTube videos on a web page and let the user select the wanted videos to play in YouTube Bulk Player.

To install, create a new folder YBPM in disk C:, i.e. C:\YBPM, and save the three files (ybpm.html, ybpm.reg, ybpm_rm.reg) in it. Double click ybpm.reg to install. Restart IE to see the new item in the context menu.

All the three files are in ascii text. You can use your favorite editor to review the code.
