I've been getting problems with my Denon 3910s progressive scan feature, playing via a Sagem Axium HD50. RGB output is fine, S-Video output is fine, but progressice scan pictures give a strange green tint, more noticeable on fleshtones. I got onto Sagem about this, and they will be updating the software of the DLP set, but they also suggested that I contact Denon and enquire as to any new firmware upgrades or fixes. Easier said than done. I contacted Denon, and to be honest they were very unhelpful. I read out the details of firmware from my machine, ESS 6609-5 Make Day 831 DRV 030825 System 6767-2 DSP 6770 CNE 20040609 Denon said these were up to date and that I did not need to "worry" myself about software/firmware upgrades. I did make the point of telling them that I found their advice very unhelpful. I am curious to know whether or not other 3910 owners have had the same issues with Denon. Whether or not Denon have supplied the necessary firmware upgrades. Or whether it is a question of finding a download and trying the firmware upgrades for yourself. I have read here that the 6609-6 upgrade is available on a site for download. Since my machine is already multi-region, does anybody know if this will affect my player in anyway with regard to multi-region. Also, if there are significant changes with the new firmware, what are the changes, and why do Denon seem so uncaring about me wanting to achieve the best performance from my machine. Any help most appreciated!!!
