Philips 824p ..how to upgrade firmware?

I have a Philips 824p with firmware 1.2 and want to upgrade it to a newer firmware version that allows me to make copies of the latest DVDs. I have an issue as for some DVDs the software AnyDVD tells me that I need to upgrade the firmware.
I’ve searched the forum for posts related to my DVD model but can only find one (http://club.cdfreaks.com/showthread.php?t=108610) and the links in there are dead.

Anyone can help pointing me in the right direction ? Thx a lot !!!
