Hi folks...
Apologies if this is a little wordy, but you'll find both the region hack and 60Hz fix here.
So I got a nice new Toshiba 42WLT66 and wanted a cheap HDMI DVD player. The LG DNX190UH fits the bill nicely and I found a region free code...
Power on the player with no disc in the drive. Press the following (leaving time between button presses):
Pause 3 1 4 1 5 9
Then key 0 for the region code and press Pause again to save.
All was rosy in the garden until I sat down to watch my region 1 Finding Nemo and found the "Introduction" video to be unwatchably jerky. A friend noted frame skipping on Serenity and finally I spotted some "hitching" in vertical pans on my Maburaho region 1 disc.
Hmmm...
Looks like an NTSC problem.
I tested the Evening With Kevin Smith Region 2 NTSC disc (since it's easier to take a player back if your problem isn't with its region 1 performance...) and found the same "hitching" on the horizontal text scroll at the start. So it's definately NTSC. Looks like it's doing the kludgy "Drop every 6th frame" 60->50Hz downsampling.
But since it's the middle of the night and Currys aren't open I decided to do some tinkering.
I found an EEPROM guide online which has default values for the US version of the player (DN191H).
To edit the EEPROM start up the player with no disc in the drive and press:
PAUSE 1 4 7 2
with the same rhythm as the region hack.
Now write down the default values
(mine were 55 53 00 d3 03 55 f4 ff your mileage may vary)
To edit the values press left and right to select a digit and press the corresponding key on the remote. To get A-F hold down 1-6.
Now change them to
55 53 00 47 02 55 f4 ff
which are the US defaults and press pause to exit.
Now restart the player (power off and power on). And cycle resolutions. Instead of 576i and 576p you should now have 480i and 480p as options. And the "hitching" is gone.
Now edit the EEPROM again and restore your default values. I did it in two goes, first the d3 then the 03, but I don't know if it matters. You should now have your original player back except... It STILL says 480i and 480p.
My NTSC discs now play without hitching, and my PAL discs appear fine with no audio/video sync that would suggest a forced 60Hz playback. I don't know if the 480p mode is actually 576p, but I'm using it at 1080i so I don't mind.
I did try altering the 03 pair to 02, 01 and 04. But was unable to get 576i/576p back as options.
Note that if all goes pear shaped go into settings/video/aspect and select 16: 9 then press 1 3 9 7 1 3 9 ENTER to do a factory reset.
Hope this helps other people. I am now much happier as my videos don't drop frames and PAL playback seems fine still...
Sorry it was a bit long winded, but figured it was best to make the experiment repeatable ;-)
The PAL DVDs I tested audio sync with were:
Love Actually (awful transfer, edge enhancement everywhere)
Coupling Series 2 Disc 1
Kill Bill Volume 2
The NTSC discs I tested frame drops with were:
Finding Nemo Disc 1 (intro video)
Maburaho Volume 1
And Evening with Kevin Smith (NTSC Region 2)
Good luck,
Stephen
