weird, something must be wrong there.
look the screenshot below, the codecs work just fine here.
Maybe it doesnt use the same codec version on v1.3c and you think it was working on v1.3c. (actually working with another version of the codec)
this is possible since v1.3c doesnt display codec versions.
I verified...in 1.3c that's work with cyberlink video codecs because the image change wjen i change configuration of codec ^^
I have this probleme on XP and Vista.........I think probleme is caused by one of compansantes of media player 11...
look at this
I have MPEG audio decoder in 1.3c too.....
I can send you all information that you want about PC but try to fix it
