I lost my recordings this morning and was about to post here for help but saw a thread with the similar problem, so i followed the reboot solution an got my recordings back!
But now I've lost the Freeview play options that appear on the bottom of the HOME Page, and when I press the "ON DEMAND" button I simply get a list of recommended shows and no way to access the Freeview play channels like All 4, iPlayer etc.
Should I do another reboot?
*EDIT* - I found the Freeview list via the "Players" option so it is just the quick access menu on the HOME page that is the outstanding issue now.
