> The attached patch adds support for incrementing/decrementing 
> timestretch by 5 units (i.e. 0.25x) using the UP/DOWN keys, 
> respectively, while in the adjust timestretch mode.  Before the patch, 
> the UP/DOWN keys caused MythTV to exit adjust timestretch mode and jump 
> backward/forward in the video.  After the patch, it's possible to set 
> 1.5X playback with only 3 keystrokes (A, UP, UP)--the same number of 
> keystrokes required to get to the timestretch menu (and one less than 
> the number required to display the timestretch menu).  Once the user 
> exits the adjust timestretch mode, UP/DOWN continue to work as always.
