Can't connect to certain people.

I've been playing games with many people. but there is only i few people I can't connect to. If I play LittleBigPlanet and invite one of my friends it says "Failed to connect players. I invited my friend to play the RE5 Demo with me and it failed but with other people it doesn't. Anyone know the problem?

Nope, the response about welcoming you to PSN is about right. Sometimes I need to invite like 10-15 times or shut down and restart before I can finally connect to someone specific, even though I can connect with others fine.
