So I brought my first mlp toy,(Fluttershy). And I got this DVD with it.. But it isin't working! It's says something about a "registration code". it was imported from th US and I brought it here in Stockholm.. Anypony got any idea how to make it work? :-/
Usually DVDs have region codes on them. The US one is it's own region. You need a region free DVD player or you'll have to mod your DVD player in your PC. Google around for info on this, and yes, you may break things by trying.
As Dragonbait said, it should work on PC, since it's region locked. If you want to watch it on tv, try connecting your PC to tv (if possible), or see if there's some additional software for your DVD player so it can play Region Locked DVD's, or if you have some console, you may get DVD software to run it (for PS2, there's PS2 player, but your PS2 has to be chipped, and for Wii, you can play it on WiiMC, but you have to have HBC for it and for installing HBC you have to have either Softmoded, Hardmoded or Combomoded Wii (Careful when modding your Wii, you can Brick it if you're not careful)). There are softwares for other consoles as well, but I know for PS2 and Wii since that's what I have.
