I usually buy my gears from my local dealer in Tottenham Court Rd, London.
As for the 3800 firmware, I'm sorry folks....I can't post it because I don't have it.
I initially bought 3800 from my local dealer, and it had the firmware installed - PAL progressive, and region-free.
After playing around with it for about 7 days, I returned it, and got DVD-A1.
And the 3800 I owned showed...

As for DVD-A1, it was not region-freed. So my dealer asked me if I wanted him to install the firmware, and I said I'd do it myself since I knew I could download the firmware from http://geocities.com/mr_merrick/denon_dvd.html
I downloaded & installed the firmware, and my DVD-A1's been working good. PAL progressive as well as region-free.
I'm waiting for new "Q" version of DVD-A1 (and 3800) to arrive from Japan to exchange my current unit. - should be here.. between end of this week and begining next week according to Hayden Lab, and my dealer.
