can play but no sound!!!!
 

it's the first time i encounter this problem......i have no idea how to fix this

Probably the file have AC3 sound and you don't have an AC3 decoder/filter. Is is also possible to be a file encoded with the old Div3 audio codec. In this case you will need DivX 3.11

one thing i find useful to use is G-SPOT its a program that will detect what video u have and if u can properly play it with ur given codecs. hope that helps some

Another useful program to give you information on your files so you know which audio and video codec is required is VideoInspector - http://www.kcsoftwares.com/index.php?vtb

GSpot, VideoInspector....(missing Avicodec).... Another usefull idea is perhaps read my Help2Help-post (a.k.a. "READ THIS FIRST BEFORE POSTING")
