Okay. Okay okay. I searched relentlessly on Google for an answer as to whether or not the Region 1(American)Veronica Mars DVDs play on any UK DVD player, but all I found were people saying "I hear" they play on them, or "someone told me so".
Well, I took the plunge and brought both series from Amazon.com. Also, upon receiving the series(just now), I wanted to give UK Veronica Mars fans the answers to their region questions. Thus, for you, I did an extensive test.
I tested all six discs of both DVD sets on 3 very different DVD players and two very different TVs.
Firstly, the TV issue doesn't exist. Considering one TV is a 2005 Widescreen Sony TV and the other is a 1999 Matsui portable combo, both worked fine and the picture looked beautiful. It all worked fine with the TVs, this won't be a problem for you.
Secondly, I tested it on each DVD player I have; an original XBox, a slimline PS2, and a really fickle Sony DVD player that normally only plays Region 2 DVDs, not even copied CDs or DVDs. All are UK Region 2, with no multi-region stuff or anything.
Well, it WORKED ON EVERY ONE OF THEM. All 12 discs of the first two series works on every one of my Region 2(Uk) DVD players and TVs. No problems AT ALL.
This is awesome! Literally no problems occured with anything; no need to wait for a Region 2 release, save yourself a LOT of money and import them.
So there you have it; Veronica Mars, series 1 and 2 work on Region 2 Dvd players. Nobody gave me a good answer to my Region questions, but I just did it for you. Import the "Region 1" Dvds, because there really is no boundary on them.
I'm now off to watch the series. Enjoy! I hope this guide helps; buy with certainty.
