The best way to use a Media Center is to access it with a Remote Control. Then you can control all your multimedia files without using a mousepad.
To do that, you need a remote control for PC. It looks like a normal remote control, except it is sold with a receiver to be plugged on the PC (USB or COM port). Maybe you already have such a remote control. It is sometimes furnished with the PC or with video cards (or tuner cards). We are giving methods to use some of these Remote Controls.

You can also buy a remote control for PC over the Web. First verify it is compatible with SesamTV™ Media Center.
