Hi i was wondering if anyone could help me, i have just purchases a denon 2910 of a friend and i am have trouble playing burned SACD-r and DVD Audio.

My firmware is ESS 6720-4 but i cant seem to find a newer firmware to update it, all the links i have found are dead

I would be grateful if anyone could help me with this matter
