Does anyone out there have a link or info on where I can get my hands on the latest firmware update for the Denon DVD 5910? Also, I have heard rumors that if your player was built after Jan/05, but before the "CI" version came out, the "CI" upgrade is actually only a firmware update, no hardware required. Is this true? Anyone performed this and been upgrade to "CI" without sending your player into denon? Please let me know...
