pal and NTSC?

[c2kdb]

hi, I have a question about pal and ntsc? I'm not sure about what to ask either. when I try to play a pal virsion game, the screen just keep jumping up and down, i can hear the sound, but the picture is just not stable. I think if i can switch my tv to pal mode it will be ok, but I can't. is there a way that i can play pal game on tv that only supports ntsc? thanks a lot.
