Hello everybody! actually this is the second time i post problems here. the first one has been solved! yay! so now i believe this forum could help and advise me how to solved my second problem. Im sorry if i post it in wrong topic. this problems starts when i first formatting my new brand laptop (dell). then, i reinstall all the program, windows xp pro and everything. unfortunately, in the end, when i tried to open a song (mp3,wav) and movies (rmvb,avi,mpeg,flv,etc), it cannot play at all. it says cannot render file (im using media player classic). (windows media player and windows movie maker also cannot play and use them).firstly, i thought it may have problems with codec. so i download from internet= storm codec. again, it failed. so what should i do now? please give me an advice!!!! sorry for my bad english..
