If you mean putting the TV on the monitor without the desktop icons, I reduce the desktop to one monitor using Settings in Display properties, click apply, enable the second monitor, click apply, choose it as primary, click apply (by doing so the desktop icons won't move), then running the TV. Works for me, however it still opens only on the primary monitor.
This is on an AIW 9600 pro with MMC 8.6 and Win2k
