Generally it wants to know what pin to start the display on. If you're using the propeller demo board that would be pin 12 I believe.

Open up the Propeller Library Demo "tv_text_demo.spin" or something like that to see how to use this object.

Chuck is right, " Videodisplay.start(pin#) - NOTE: Only put the lowest numbered pin in which your video DAC starts on, and it must start within a multiple of 4 pins and all in the same group, ie.- 0,4,8,12,16.. ect.
