some of trailers which i have dlded from roth.ru, have no sound while playing (spartacus, the bone collector etc.). i think this problem because my software and codecs. what codecs and players you use for divx files playing?

I use:
Players : RadLight, VPlayer or Windows Media Player 7.0
Codec : DivX 4.11 Codec

So far it worked with every DivX file i have!

these trailers are using the Divx 3.11 alpha sound codec, basically a hacked version of .wma(audio) codec. So in order to play these Divx trailers u need to install the old divx3.11 pack(includes the sound codec), if u have Divx5.02 installed, video will use 5.02 codec but will play with the 3.11 sound codec
