There are several websites that post links and how-to’s for software mods (called hacks) for dvd players that will enable multi-region playability. Start with videohelp.com
I don’t think altering the firmware of your player to allow multiregional play is illegal in the US. It is in some countries. I found out about the above website from a recommendation in the askjeeevs database while looking for something else. I don’t think jeeves would advocate illegal activity or post a link to a website that supports illegal activity.
Some people feel that enabling multiregional play is not stealing anything because you paid for your region-3 dvd, all legit and everything. When you buy a dvd you also buy the right to decode it and watch it, for your own private use.
I feel that the media corps have a right to market their product as they see fit, to their greatest profit potential. If that means limiting product releases geographically, then so be it. But I feel those arbitrary marketing boundaries would/should apply only to businesses. Any business that would display/decode a dvd out of its region is stealing from the marketing potential of the media corps. As an individual decoding a disc for personal use, you do not interfere with the marketing schemes or profit potential of the media corps.
I looked for anything from Denon that disclaimed warranty liability for altering a dvd player’s firmware. It isn’t there, but I wouldn’t be surprised if Denon refused to do any warranty repairs if your alter the firmware. I bought a Denon player specifically because multiregional hacks are constantly being made available for it, tho I haven’t done it.
Oh, btw, there is a multiregional dvd hack available for your Denon 2200.
Off Topic: And for anyone with a Motorola v710 cell phone on a Verizon plan, there is a hack available online to enable the BlueTooth functions that are available with any other plan provider, that only Verizon has disabled, and is being sued over.
