Play NTSC U/C on NTSC J PS2

[Woo]

Thanks for your info!
I was reading the forums more yesterday. I found that I can't play orginal but I CAN play backup. So, if I purchase a DVD-R drive and back up the orginal games, I don't have to worry about the U/C or J. Is that true?
If a DVD-R can solve the problem, I think it worths the investment.
Thanks for answering my question.
