ripping RCE disk: problems

[noobsaibot]

Hello friends:

I'm having some problems when trying to make a backup of this protected disk.
I'm in region 4, the referred disk is 4 and my DVD drive is set to region 4 as well, also, I am using DVDDecrypter 3.5.1.0.
Well, when I choose Mode->ISO read (the disk is DVD5), the log shows:
W 15:43:43 Possible RCE Protection Found!
W 15:43:43 Media region code: 4Then DVDDecrypter pops a window asking me to choose the intended region for this disk, but the only selectable option is 4, it's ok, my region is 4 anyway, then I click OK, and the log:
W 15:43:51 User selected Region 4 for the disc's region code.I start the rip, and it completes OK, no problem, but when I mount the image with emulating program, or burn this ISO, I get a blue screen, saying this disk was not made for this region. So I guess it's a RCE type problem.

Can you help me out, the only settings I've made on the configuration is: I changed (in the ISO read mode tab) so that the last 2 boxes are also ticked:
-Remove IFO/BUP PUOs
-Remove VOB PUOs

For this 1 disc, try unticking the remove RCE protection box for whatever mode you're ripping in.

It could just be that the IFO files dont actually want region 4, but that's all the disc is set to allow. Without seeing the original IFO files, I couldnt say for sure.
