[mythtv] patch to fix strange display position in EPG

[Takeru KOMORIYA]

Hi,

When I set minus values for "Horizonal over/underscan percentage" in
playback settings and bring up the EPG, position of the area for
displaying live TV(should be at upper right) goes to upper left.

Here's a patch which will fix the problem.
It also fixes the typo in message.

Thanks in advance.
