The distributed V13 package is missing the ExeDir.zip required for subtitles downloads in Movies+. It is attached here.
Also the Playlist Search script in YouTube+ needs to be replaced with the attached due to a YouTube change.
Lastly when searching/playing YouTube Videos ensure the Video/AutoPlay Next Video is not set to Shuffle.
These are all corrected in V14 for WIIMC 1.2.8 which is on hold pending resolution of the 1.2.8 SMB problem.
