Posted to the "other" forum in the bug reporting thread, but hought it would be useful here too.
I'm experiencing the stretched 4:3 display problem like others, but only saw reboots being suggested to fix the unresponsive * key.
I've found that after you change to a 4:3 channel and its stretched and the * key does nothing, that if you press "guide", then "Cancel", the * key magically operates as it should.
Hope that helps other in the meantime (reboots take too long!)
