[corrosivo]

I need help from you guys.

My PS2 is a 30001 USA, with (I'm almost sure) a NEO 2.2. I swap discs with DVD region X. The thing is that DVDs work perfect, but I can't boot DVD region x. I get the annoying clicking sound. I am able to boot PS1 backups though, but not always. I really don't know which are my options. I am planning on buying a Messiah the minute it goes out for my v3 USA console, but meanwhile I want to fix this situation.

What do you think is the problem?
Thanks in advance
