In game XMB not working in all games?

Apperntly a number of games do not work with in-game xmb on the ps3

"I put enchanted arms to play for awhile. It seems In-game xmb doesn't support enchanted arms.
I check my other games. Hmmm..lost planet does not seem to support it either.
What gives? Hopefully we will get a patch in the near future.
the Japanese version of Valkyria *According to gamer, Le-mo*
Call of Duty 3 *According to gamer, theycallmeryan*
Blacksite: Area 51 *According to gamer, theycallmeryan*"

Strange, I have enchanted arms and it didn't work for me (first time that game has been in my ps3 for a while..whats with the weird gay tranny dude????)
