Page 1 of DVD PLAYER HELP?

Please can anyone out there help me as I would like to know if any of the following DVD players can be remotely hacked to be multi-region.

JVC XV542
Phillips DVD622
Pioneer DV444
Samsung DVD105
Sony DVP NS300
Sony DVP NS400

I have already checked out the multi-region hacks page on this site with not much luck, but the Phillips looks quite technical to remotely hack, do I have to purchase another remote control to convert this player, please can anyone advise me if I choose this player on how to convert to multi-region.

I would be very grateful for your help.

Kind Regards,

For the Philips:
As I understand it, you can use the standard remote to change regions, but this will only work a finite number of times (up to 25?), after which your player will "lock" in the selected region.
You can make it multi-region permanently if you have a "learning" remote (as manufactured by One4All) with a "magic" key. These remotes can be programmed to send the correct infra-red code to unlock the player. The standard remote cannot generate this code.

Hope this helps...
