48 It looks like some distro maintainers disable this update checker...
49 This is a very very bad idea. Main reason: in order to play Youtube videos
50 with SMPlayer a very recent version is required. Distros usually provide
51 ancient versions...
52 If you remove the possibility to inform the user about new versions they will
53 probably use a version with broken support for Youtube like forever.
54
55 If you still want to disable this option, the correct way to do it is by
56 removing the UPDATE_CHECKER define in smplayer.pro, and not by removing the
57 following code.
