Cyrius and Belgabor are working like crazy, the aim is to get all the additional functionialities of VdubMod ported to the Vdub 1.5.x sourcecode, and this is a huge task as Avery changed a lot from 1.4.x to 1.5.x ... In this process Cyrius wants to make the OGM ( and also matroska ) implementation much cleaner as it currently is, at least thats what i understand, and there will be Vorbis audio decoding built in for preview mode.
