A few tasks (notably tvflag , but also tvdisp in its movie mode) can use a ``control panel''. This is a panel of buttons that pops up, with each button performing some interactive function associated with the TV device. Although always used in unison with the TV device, this control panel is strangely a separate executable, which must also be started by hand. To do this, give the command
% xpanel &to the same computer that you are using for xmtv.
