 The mythfrontend video library will occasionally deadlock if you attempt
 to exit back the video list, too, quickly -- and sadly the terminal output
 didn't indicate any error.

 Steps to reproduce this issue: (this does not reliable happen for me, but
 it does from time to time)

 {{{
 1) Go to the video library
 2) at this point you have two options:
    a) select a video and press p (from the video list) to start playing
    b) select a video and press enter (from the video list) to see details
       about the video where you can select 'watch'.
 3) I often use option '''b''' above (but I think it does happen in both
 cases)
 4) when the video starts to play -- if you quikcly press esc twice to
 get back to the video list -- sometimes, but not always, mythfrontend will
 deadlock and you have to forcibly kill it from the terminal.
