Hello; I was pleased to find this site, and hope someone here might be of assistance. I'm looking for any possible region codes for the Zenith DVP-615 model as well as for the Bose 3-2-1 Series II system. I have located a couple of relevant listings here on the forum, but for unclear reasons, the codes provided did not work for either player when I tried them. In the case of the Zenith, this may be due to the fact that my machine was manufactured in September 2007, at which point the codes must have changed from previous models. Again, I'm grateful for any help you can give.
