Ok so I've been looking around everywhere on tons of forums which discuss this issue and I still haven't got an answer which can reassure me about this.
So...
I own a PAL PS3 and play on a PAL SDTV. I want to import Modern Warfare 2 from the U.S because I know that PS3 games are region free. Now the issue is, apparently some games have a problem with compatibility when played on an SDTV from a different region because of their different resolutions. However some say that there is no problem with a PAL SDTV playing NTSC games on a PAL PS3 but only for those wanting to play PAL games on NTSC PS3. I'd like to believe this because PAL SD resolution is 576i, whereas the NTSC SDTV resolution is 480i. So that means that there would be no problem playing NTSC games because PAL tv's should be able to lower their resolution to 480i to play them. PAL on an NTSC tv would be a problem though because the resolution would have to be higher than the tv can handle. Am I right or talking absolute shit?
Any help would be appreciated because my Sister who lives in the U.S wants to get me Modern Warfare for christmas but doesn't want to risk sending it to me if it's not going to work..
