I bought a 3800 yesterday, and brifely checked it. It's region-free with PAL progressive enabled. My dealer doesn't usually know much but he said the firmware region hack was done using firmware update. (not modding a chip) Does firmware which enables PAL progressive exist? According to http://www.dvdupgrades.info/cgi-bin/shop/50014.html to enable PAL progressive 3800 has to be modified internally. Could anyone confirm this please? (again, my dealer said it's only done using firmware update...but he usually has no idea. ) I confirmed the PAL progressive. (my projector says 575/50p when I played some R2 discs.) Anyway... I didn't have enough time to check for chroma upsampling error. On the 3800 you can check the firmware version by depressing PLAY and OPEN/CLOSE on the player whilst powering on your player. On my 3800, pressing DISPLAY on the remote shows : ESS 720 Pressing MENU on the remote shows : ESS 625P PANEL 6093 DRV 6100 Does anyone know if this firmware is a fix for chroma bug? Thanks.
