I have got the latest k-lite and real alternative. It wont play SOME of the rmvb from Asia. You would hear no sound if play it with MPC but fine with real player. I check the properties and dont know what is the difference between the playable rmvb and non-playable rmvb. I use MPC because it has a fast snapshot button (F5). What other players is as good?
I would get the opposite effect. you can hear it, but you can't see it. I would look at AVS4ALL or AVS Media Player. It will play pretty much all formats. Then if you want to, you can convert your media to any format you wish with AVS Converter 6.0
