Oppo 103 firmware

I just updated mine today and now the YouTube search screen is too large. The search field is out of view and I've tried every possible video setting in the main menu.  It's not a video setting in the TV (Sony LCD) but something in the player itself.  I'm stuck.  Is there a way I can revert back to the former firmware version?   

FYI, Oppo owners: 103 & 105 can now be used to rip SACDs! Google it, I know people who've done it successfully. Could be a lifesaver for a few out there with big SACD collections. Cheers,

This may explain some issues I had with the player being used as an HDMI switcher.  I was feeding a Linux desktop through it and every now and then the image would just lock up.

Thanks! :)
