How to set TCPMP as default player?
 

Does anyone know how to make TCPMP the default music/video player, so that when I open videos in "camera album", they open with TCPMP instead of WMP(which sucks because the audio/video is always not in sync for WMP)

Open TCPMP and go to Options > Settings > Select Page > File Associations -- and choose the types of files you want to open with TCPMP instead of WMP.
