Page 1 of Grundig Hack

I have got a Grundig gdv220, i can`t find this model anywhere on the web. I got it from Currys. Apparently the Grundig hack of 0 1 2 3 Play should work on all Grundigs, but surprise surprise it does not on mine.

I have 4 region 1 dvd`s, Dante`s peak, Jurassic park, The Haunting and Twister.

Dante`s peak is the only one that seems to work. Strangely it works on region 2 aswell.

What can i do ????

Please help !!!

use the hack for the orion dvd 2000 ,,make sure u use the buttons on the actual player not on the remote........
