spurious keyboard input on intel macbook to blobwars and mplayer

Binary package hint: mplayer

If I attempt to use mplayer to watch something, it behaves as if I'm sporadically pressing the left arrow key. I can only watch a few seconds before it rewinds, sometimes it just loops right at the beginning: 'tic tic tic tic tic...'.

I filed this under 'mplayer' figuring it would get more attention than under 'blobwars', but blobwars seems to be similarly broken. Attempting to configure the keyboard settings in blobwars is almost impossible; it's as if they keyboard is constantly providing input to the application, and the setting keeps counting down. Where I would want to select "Right" (for the right movement key, for example) the setting changes, as I watch, from "Right" to "Down" to Up, Equals, etc. 9, 8, 7, 6...etc. If I attempt to configure one of the horizontal slider settings for brightness, volume, etc., the slider ticks to the left as I watch (without typing anything).

I have never noticed any strange spurious input behavior on the command line, in vim, in text-entry web forms (such as this one), or OpenOffice, etc. So far, just mplayer and blobwars. I would guess they're using a special interface to notice keyboard input, and that interface is broken. There are probably other applications with this problem but I haven't noticed them yet; I don't play many games or spend very much time watching videos.

Overall, though, *very* nice job on the MacBook in Feisty.
