Sony DVD players are almost impossible to hack. The site below has the most comprehensive listing of hacks anywhere and it looks like there isn't one.

If you Google "Sony DAR-RD100 DVD Hack" you may get an answer but I'm fairly sure that Sony DVD players can only be altered through a chipped remote. I think that these are "hired" for about £15 - £20 and then returned once the hack is completed.

Sorry I can't help further than that.

I have a huge list of unlocking codes but Sony are pigs to unlock. I e-mailed the guy who sent me the codes and he says that Sony are one step ahead of us and know that we will try and do this. So, to be able to unlock a Sony you have to buy a piece of equipment that costs about £45. I never bothered when he told me that, it would be cheaper to get a different dvd player. Sorry i can't give you a code but hope this helps.
