Hello everyone. Long time reader, first time posting. I have the following equipment that I would like to purchase a universal remote to control everything. From what I have read on the board it looks like the Home Theater Master SL-9000, or the Sony RM-AV2500 may do the trick. My main concern is that I am able to use the "IO" button and the "PIP" buttons.

Television - Mitsubishi WS-55819
Home Theater - Pioneer VSXD409
DVD Player - Pioneer DV-578A
Digital Cable Box - Scientific Atlanta Explorer 4200HD

Thank you in advance for any help you can provide.
