Any Tips On Playing DVDs From another Region on a Laptop?

OK, So I did have an Unlocked DVD player... But It broke... So, I want to play some of my Region 1 (NTSC) DVDs on My Region 2 (PAL) Laptop... but the only way I could get it to work is if I switch my Region... But I can only do it so many times... And 90% of my DVDs are pal and I REALY don't want to tempt fate...

So, any of you guys got any hints or tips? And hey, let's keep this open for all so post Mac, PC and Linux solutions, for completionists sake!
