firmware (software updates) changes are better than mods becuase you continue to enjoy the benefit if the warranty as more often then not they are unofficial discs produced by the company who made the dvd.
who do u blame if u have a fault on the player and its been modded. ??? Look at the denon thread 3800 you would hardly catch anyone modding with a chip within the warranty period even though the mods are out there to do it.
If I buy a Panasonic All in One, as region 2, does anyone know if this would need to be chipped, or a firmware (??) update to be made multi region? Also how much is this likely to cost, and would a local Panasonic dealer do this, or would I need to elsewhere to get the machine modified?
