I was watching for such video player for my Kubuntu for a long time. Thanks to Ricardo Villalba for making my dreams come true :b
MALWARE WARNING - I downloaded this but my antivirus program gave this warning. The file 'smplayer-14.3.0-win32.exe' contained a virus or unwanted program 'ADWARE/InstallCore.Gen' [adware] Apparently there is unwanted adware bundled with the product. You may be able to decline this during the installation. I hate this sort of sneakiness and I didn't trust it at all. I've now deleted the file completely.
Works nicely, and doesn't have the YouTube problems its little brother UMPlayer currently exhibits.
A great player, the only thing I miss in it is adjustable time for shutdown or shutdown the computer after watching the film. So often I have switched on SMPlayer to watch and Bestplayer the computer turned off after the movie I fell asleep.:D
