Most DVD players can be "cracked" but still you need to worry about the NTSC/PAL conversion issue.
I watch all my non-NTSC and non-region 0/1 discs on my computer.
Computers are able to display NTSC & PAL correctly unlike TV sets in America.
By default, DVD-Rom drives will "lock up" after you change the region code 4-5 times, however, to override this you can simply download a region-free patch for like 700kb. That's less then a megabyte folks!
Cracking a DVD-Rom drive in a Mac is way more complicated compared to a IBM compatable PC.
