Here is the specific instructions I got from an LG Hacks site which I used to make my DK9934N region-free
(this was confirmed by the local LG service center):
Power on the player with no disc in the drive
Wait for the "No Disc" message to appear
Press PAUSE the Remote
Enter 3, 1, 4, 1, 5, 9 on the Remote (the word REGION 3 appears on the
display, if it doesn't change, try it again).
Enter 0 on the Remote to display REGION 0 (0 = All Regions, 1 = Region
1, 2 = Region 2, 3 = Region 3, etc.)
Press Pause on the Remote ; then press STOP.
Power the player Off, wait 30 seconds and then power back On
Btw, I played a downloaded DIVX (When Harry met Sally) and a self-created Divx (Troy) and they both played
w/o any hitches. It also played Mpg movies, mp3. and wma music files flawlessly and jpg pics. It cannot run
ordinary AVI videos. (Note that Divx has an .avi extension also.) FF is up to 100X.
Volume control on the remote is applicable only if your TV set is also and LG brand.
