If I want to display a video for an hour and then switch to full-screen TV, I need to make a screen file where the background is simply set to a TV source, but this gives me no option to set the TV channel -- it'll simply display whatever was the last TV channel on display.
It seems that the only way to automate which channel the TV is set to is to display the TV as an area (as opposed to the background), and within that area's settings I can choose the channel to display. So the best solution I can think of right now is:
If I want a video playing from 1pm to 2pm, then MTV to display from 2pm to 3pm, then the only way to ensure that the screen will display the MTV channel is to edit the 1pm to 2pm screen file so that in the last minute (at 1:59pm) MTV pops up in a small window, then when it switches to TV mode at 2pm it will display MTV because it was the last channel on display.
Is there a better way to do this?
Many thanks in advance for any help.
