The only workaround is to use the sharing option for now. JW player lets you add videos to its playlist, but the subsonic playlist does not work with videos yet.
If you display a folder with more then 1 video then put a tick in boxes next to the vids you want to share Then scroll down and in the more actions box - select Selected Songs (sic) - Share
Everyone is entitled to be stupid, but some abuse the privilege!
Due to the confusion from too many genres of music, we have decided to put both country music and rap music into the genre of Crap music.
Thanks for clarifying that, ytechie and BKKKPewsey.
I tried the "External player with playlist " option with some success. I am able to play the flv files successfully with VLC. But I would like to use the same with Winamp. Winamp accepts the .mp3 files/playlist but not the FLV files.
