New description:

Aspect ratio is calculated incorrectly on systems with two monitors.

Prior description -
Video playback with mythfrontend now has the wrong aspect ratio. Also the
on-screen "Paused" display has disappeared.\\

~~A version of mythtv master compiled two days ago is correct; a version
compiled today is wrong.~~

Attached are two screenshots of the same recording with the different
frontends, both paused at approximately the same moment.\\

Version of the old/correct mythfrontend:

Comment (by Stuart Auchterlonie):

Replying to [comment:11 Peter Bennett]:

> Set up a unique user id for Mythfrontend.
> Log on with that user and use display setup to disable one monitor.
> Every time you logon with that user you get one screen, when logging on
with a different user id you can use both screens.

Realistically this isn't the best approach. My dev frontend systems have 2
monitors
connected, which allows a nice testing setup (ie. debuggers, code etc on
one screen,
and the frontend on the other screen), or watching stuff you need to catch
up on whilst
doing some other stuff at the same time.
