Like many others when I got my HT-D5500 Home Theatre Blue Ray Player I upgraded firmwares as an when they were available.
Unfortuneatly one of the recent firmwares introduced cinavia to my Blue ray player.
Thank god for this site and excellant work in providing a firmware downgrade facility

My HT-D5500 is now Cinavia Free!! Many thanks.
What I need to know now is what is the most upto date Cinavia Free firmware for my system??
Is the "downgrade firmware available via the DNS Downgrade fix" the latest "Pre-Cinavia" firmware?
Or do I need to upgrade??
Reason I ask, is that it appears since the downgrade that .MKV's no longer work?? (I only have 3 MKV's that were downloaded today and
none work as Hard drive went tits up with my entire collection on)
If I need to upgrade Firmwares, which version and where from??
Many Many thanks!!
