I've downloaded the newest version of Media Player Classic from here: http://www.free-codecs.com/Media_Player_Classic_download.htm
I like this new version especially because of the disabled dvd navigator's software region check. On the other hand, I can't play ratDVD-movies anymore, when trying to open this file format, the program reports "Can't find DVD directory". This was no problem with earlier versions than 22.214.171.124!
I'm thankful for any hint!
Thanks in advance!
