Ok, version1.1.43 of Pierogi is now working its way up to extras-devel. This one has the new TV-oriented menu panel. (DVD/BD/etc. devices should automagically continue to use the old menu panel.) I went through the entire list of TV keysets, but pretty much only LG, Samsung, and Sony TVs are using these new menu buttons. (And I've only been able to find a "back" button for LG.)

As always, beware new bugs! Thanks.

EDIT: Btw, what would folks think about renaming the menu panel something like "navigation" or "options" or the like? Since I'm cramming items like "Guide" and "Apps" onto this panel, it's starting to move away from a just the basic "menu navigation" concept. Anyway, just an idea...
