Is it Power DVD14 asking for the region or Windows ?
Your new Pioneer Blu-ray player needs to have its region code set for DVD's only and in your case that would be region 1 _ USA.
Since we are talking about DVD's this does not apply to Blu-rays, there region is determined by the disc and that would be region A,B or C.
To set the region of your Pioneer player for DVD's go the "Control Panel" > Device Manager > DVD/CD-Rom drives.
Choose your Pioneer drive _ double click to open that.
In that window in the heading bar there will be "DVD Region"
Choose USA for your country and that should fix it to region 1

Also know that the DVD region code on a DVD rom drive is embedded in the drives firmware, so once the fifth and final choice is used up, that's what it will be set too and there is no way to undue it.

Jeff,

I'm not sure what is going on. It is definitely Power DVD 14 related. The Blu-Ray region(A) resets listed in PowerDVD 14 is still showing as 5 resets available, but the hardware/firmware information in the control panel for my BD-Rom shows only 3 resets remaining, and it *is* set to region 1.

In PowerDVD 14, under settings/information it states:

Player Information:

Player region code: Not Specified
Current drive - F:\
Title region code: Not Specified

It's odd that it would say "not specified", as this is with a DVD disc in the BD-Rom drive.

I have the same settings in mine:
And I haven't even bothered to set the region code.

Player region code: Not Specified
Current drive - F:\
Title region code: Not Specified

Go into "Auto Play" in the control panel and make sure that Power DVD 14 isn't going to play the DVD automatically _ set it to "Take No action". I believe it's under "DVD Movie"

Save the selection, insert your DVD into the drive and play it with Windows Media Player.
Do you get prompted to select your region in Windows Media Player ?

If not then I would say it's an issue directly related with Power DVD14 and unless someone posts here with some more suggestions to fix your problem, I would create a support ticket.

You could try re-installing Power DVD14, sometimes that cleans up the registry.
Save your install file to the desk top and install it over top of what ever version you have now.

A more aggressive approach to this to totally un-install it, run CCleaners registry cleaner as many times as necessary until it finds nothing and then re-install it from the desk top again.

If it's an upgrade, you can still do a clean install _ install your upgrade version and you will be prompted to enter you old key from your previous full version. This will enable you to do a clean install from an upgrade version.
Doing a clean install rather then installing new versions over top of old ones sometimes can cure problems like your having.

Once you have installed a clean version, head over to the software update page and install the latest patch _ this time on top of what you have just installed _ restart your machine.

Again, this may help with your problem, but there is no way of knowing of this will work.

OK, doing this fixed my problem. Setting it to take no action did the trick.

I wonder why the seperate Windows settings would have anything to do with this, though? From what I can tell, it is PowerDVD that is "auto-detecting" disc insertion with one of its hidden processes, because it still detects the DVD or Blu-Ray disc and loads the movie information in the PowerDVD window, but doesnt actually start auto-playing it now.

Maybe there is a seperate windows process that is detecting the discs region when auto-play is enabled for Windows Media Player purposes?

At any rate, thank you for the fix.

Odd behavior, it shouldn't be doing that and selecting Power DVD14 not to play a DVD automatically isn't really a fix.
Sound more like a bug that needs reporting, but a song as you happy.
