Page 1 of Sony DVP-C600D (5 disc)

I`m looking the way of make code free my dvdp, but I haven`t found anything about this model, my dvdp is Region 4, I think that the modification has to be by hardware, tnx for the information to hack this player.

Did you get any response? I have this DVD on Zone-1 and would like to multi-zone it.
Thanks.

Sony region-1 DVD players/recorders can never play PAL DVDs. So if you want a truly multiregion Sony unit, you have to start off with one sold as a PAL player for region 2 or 4 - and those can also play NTSC DVDs.

However, it`s worth trying the hack for the GXD500 if you`ve got a Palm-Pilot or a Laptop with IR or an OFA remote:

Or since one or two Sony`s are rebadged LG`s then try the Sony hack CD. I believe that you extract the file from the zipfile and write it to the root directory of the CD:

It`s possible that you will then be able to play NTSC DVDs from other regions like Japan, so if you do try the hack, tell us what happens.

The factory commands and machine ID are different to non PAL capable machines, and the unit will simply ignore the PAL service commands.
