I think region 2 uses PAL so even if you were to remove CSS encryption and region coding on the disk, the US PS3 won't play it. I have a US PS3 and find I cannot play Region 4 titles even if they have no region code on them - the PS3 complains about not being able to play PAL discs.
There is a way out of it. Rather than create a DVD image of the title, use DVD Shrink or whatever to rip the 4 or more vob files into one large vob file. If it's less than 4G burn the one file to a DVD and that will play on the PS3. It seems that while the BD/DVD player in the PS3 will not play PAL titles (for a US PS3) XMB doesn't care. And with the latest firmware you can get some of the upscaling features that are in the BD/DVD player
