for sum movies files, it says like sending information downloading codec, and then it has an error, then i get no sound, can any1 help me with this?
Well it most likely would be trying to get this codec http://www.afterdawn.com/software/video_software/codecs_and_filters/divx_3_codec.cfm but there is no way of telling for sure unless we know exactly what codec is required to play your file!
and this program should tell you exactly what codec you need http://www.afterdawn.com/software/video_software/video_tools/gspot.cfm
