uninstall .81 and go to this thread
http://forum.ppcgeeks.com/showthread.php?t=6623 . A problem I am having after fucking around with .81 and gapi (gapi will still be there after a hard reset, it's a bitch to get rid of), is that now I can't stream .asx through Windows Media Player, which totally blows.
Go with .72 and the flv 1.4.2 , trust me.
