TCPMP is quite good but sadly is no more in development
CorePlayer Mobile is quite good... but you need to pay like RM 45-50++ for the registered version

BTW CorePlaer Mobile features a intergrated YouTube player and also include a optimize version of qTV display driver..... so you don't have to download the Google Version of YouTube player (which work horrible.... cause it use RawFrame Mode to display those video and i can tell you the video is very choppy..)
