[mythtv] Interesting Bug. . .

[DanM]

On mythfrontend, if I happen to hit "Space" twice in quick succession on 
an item like "Games" Or "Watch TV" it launches that portition twice.  
Its not so much of a problem except with say Watch TV where I get the 
message that mythtv is out of inputs.

I propose having the various frontends wait a minimum of .25 seconds 
before accepting another input to prevent stuff like that from happening.
