How to find out what firmware is on my WD TV Live Plus box?

I have a WD TV Live Plus box.  How do I know what firmware it is using?  And if it’s not the latest from WD, will installing the newest firmware fix these issues I am having:

1) There’s an MKV movie file that the WD TV box won’t open up, but I can watch it fine on my PC using VLC.  But I can open up other MKV files using this same WD TV box.

  1. Whenever I have a movie file that the WD TV box can’t open, all subsequent files will not open up either.  But these subsequent files used to be able to be viewed before.  So I reboot the WD TV box, and those subsequent files will then view OK.

It is in the ABOUT screen under settings.
