If you are creating your media listing, it is assumed that you have gathered all possible information by then.

oh.... so i can't update them once i called xbmcplugin.addDirectoryItem() ? alright. thanks!
no wonder, i tried to creating a thread that would get additional information after i finalized the directory, passed the list item as an argument to the thread and updated afterwards. but it doesn't reflect.

Thanks for the info Roman_V_M
