Hi all, I too have a problem with this crazy codec. The sound is coming through really really low on my PC. AVICodec says that AV3 DVM is unsupported. I tried following the link mentioned and downloaded the software, but that didn't work. so I installed an AC3 codec too, that didn't work. So I tried "the codecs" pack and installed everything, but that didn't work. Can someone please tell me what I'm doing wrong!!! Thanks, Paul (frustrated!!)
