As far as I can remember, it plays videos too albeit not full screen... sorry, I dun hv my old W850 with me now otherwise wud hv told u the xact steps.... Regarding the matter of continuous askin, u have to set its preferences to "Never ask.." by using the application preferences.. Go to "Applications" menu, select KDPlayer, press the key for "More" and then set the "Permissions".. Allow it to "read user data" and "write user data" by setting those options to "Never Ask"....
it is still a development version I think, so u hafta follow the developmental threads on the net for newer versions.....
Ok.. on second thoughts lemme give it a try...this procedure is from my memory.. it may be wrong... go to Menu>Playlist>Add New Files. Browse the filesystem and add compatible mp4 video files.. and it will play them flawlessly (except for the full screen part)...
r u using a K series or an old W series phone?? ... Walkman 2.0 player supported album art !!!
