Why can't my iMac play my DVD?

[esploded]

I have the last generation iMac that was released last summer.
I recently took a trip to Japan, and I thoroughly enjoyed the randomly hilarious television there, so I borrowed my friends' DVD recorder and TV and burned a few DVDs of the shows. It's in region 2, is that why I cannot play these videos? I've tried VLC, Ripit and Mactheripper (both won't recognize the DVD) and handbrake. All have failed. If I get an external DVD player that I set to region 2 will I be able to watch them?

seems to suggest its possible with using Handbrake

Probably the region code. But maybe it's because it's some kind of Japenese weird DVD format .

Have you finalised the DVD before taking it out?

all Dvd's have region codes and ur not supposed to be able to play a (for example) a Japanese DVD in America. They do it with video games too, idk how to play it u might be able to rip it using handbreak that might work. u can probably look up how to remove it, or just play it ask here or try google.
