Question for anyone who has updated firmware for their Panasonic Plasma
 

I have a TH-42PD50U Panny plasma and just recently updated the firmware. I noticed that now, when watching an anamorphic DVD, there will be no black bars on the top and bottom of the screen if switched to 4:3 mode. This is not a big deal because I wouldnt watch it in 4:3 mode anyway, but before the firmware upgrade, there would be bars on the top and botom of the screen. Has anyone else updated their firmware on their TVs and noticed this also?
