Yes the drv 1-69-0 ess9104-3 does have lipsync problems. I have got the same firmware as on the Italian site from another source (Denon cd). Both are exactly the same when compared in a hex editor
After having a look at 2800II firmware files with a hex editor, I am now convinced that there is a hidden menu.
Within the firmware there are many references to extra features, a 'Factory control page', region selection, macrovision & CSS options. DVD-A1 & 3800 firmwares contain similar references.
There is also aparently another new firmware that some dealers have DRV 6200-2 & ESS 9104-3. Someone must have this?
i have got a new cd (got it from my dealer via denon) drv 3-16-0 ess 9104-3 has sorted out my pal p problem and so far lip sync looks good although I have not had any lip sync probs so far with the previous update that I paid for :-(
The official Denon PAL progressive firmware has been released.
Hunt about a bit on the web and you should find it. It's not multiregion though but thankfully I've not encountered any problems so far. So I'm very pleased. The previous version 9104-3 was awful. Picture breakup, freezing, sluggish controls e.t.c.
