Bitten with the firmware update bug I hunted around for an update to my DVD player – the Denon 2910. The player has been excellent but I remember reading that there was a firmware update that improved picture quality (especially blacks) over HDMI.
A search on AV Forums produced the answer. There have been several firmware updates issued since last year, the most recent and multi region from December 05. Visit the (unofficial) Denon 2910 firmware page and download the version required. Follow the instructions on the site or on the thread and you’ll have a lovely up to date multi region player. There were notable improvements in the picture quality over HDMI so it’s a worthwhile upgrade.
