Bug with DVD Menu navigation keyboard shortcut left and right

Hello,
I tried to play a DVD with MPC (I didn't did it since several years), all is OK for playback off course, but there is a problem with the keybord navigation menu shortcuts :
It's impossible to navigate to the left or the right menus with alt+left or Alt+right arrow. All is OK for up and down navigation with Alt+up or down arrow
I didn't modify anything in the keyboard shortcut configuration, so the shortcuts Alt+left or right arrow should be correctly configured.
All is OK with mouse, but the problem is that I wanted to reconfigure my Remote control (IMON RM100) with MPC-HC, and it depends of keyboard shortcuts.

OK I found a fix, you need to create an other shortcut (ex Ctrl+Alt+left or right arrow)
This seems to be because shortcut Alt+left or right arrow is already used for an other shortcut : jump back or forward (large) for videos.

Thanks for reporting. Yes, the default keyboard shortcuts need to be changed. I will make sure that gets done in next version.
