I have read lots of the posts regarding sony multiregion hacks but couldn't find an answer to my query.
I don't have apda nor did I really want to buy a chipped remote to convert my dav-s400 system from reg2 to multi. Is there any other devices I can use to region hack this machine. i.e. PC with infrared device. Infrared nokia mobile etc etc!

Any help would be great.
