I installed the OS X security update last night. When I synced my iPod today, I got a message saying that some of the files could not be synced because they were not compatible. All of the files that were listed were shows I recorded from the TV and converted with QT Pro to play on my iPod. They have been on there for months, but this is the first time I got this message. Does anybody know if the update has caused any such problems for other people? Thanks, Kevin
