A quick update regarding the Panasonic semi region free post I made here. Someone had linked to my post on a French forum, suggesting (from the google translation at least) that while it worked on the Django disc, it doesn't work on Criterion, Scream Factory and Fortune Star blus. I don't have any Scream Factory discs to try, but I do have a number of Criterion and F.S. titles to try and they all work perfectly as I described in the post. However, this made me decide to go through the rest of the region A discs I have at hand, and the results are a mixed bag to say the least.
If you're looking for a true multi region player then the Panasonic players will disappoint, as during testing a number of blu rays from different companies proved to be incompatible. In almost all instances this appeared to be down to the disc having been programmed to not respond to any button presses other than eject, meaning it isn't possible to press stop before pressing top menu. The first I found was the Canadian Vengeance trilogy release, with all three films refusing to co-operate. Other discs that fall into this category include Vexille from Funimation, Lone Wolf And Cub from AnimEigo, Drive from Sony Pictures and everything from 20th Century Fox, amongst others. Hong Kong wise, they all work other than The Storm Riders from Universe.
As always there are anomalies, with a couple of discs refusing to work using the stop/top menu trick, but if you then press 1 and ok they will play and the menu can then be accessed, very bizarre. A good example of this is the Mill Creek double bill budget release of Keoma and The Grand Duel (A surprisingly good disc btw).
So, it isn't quite the multi region dream machine it appeared to be, however a player that unexpectedly plays Criterion discs along with many others it shouldn't, is still a bit of a bargain!
