Keyboard input is ignored during video playback

[Daniel O'Connor <darius@…>]

I find that some times Myth ignores keyboard input.

It comes and goes (without restarting), however the remote and mouse work (eg the wheel skip back and forth).

The keyboard is working because ctrl-alt-f1 will cause X to go to the text console.

I don't believe it's a focus issue because it doesn't go away if I click on the window (and mouse events work).

Note that the keyboard works perfectly in the menu system.

I am running twm as the window manager if it matters.
