Have you got one?
I e-mailed http://www.multizonedvd.co.uk who are the only people I know selling them and they would only give the hack if I bought the player.
I have the Mico A980 which is good but at the time one of the only DVD players with Mp3 and Macro disabled.
You can now get a Pioneer 340 chipped for region/macro free for £180 and other big names now play Mp3.
£190 is looking a bit steep now!
