ok, I checked this and avid creates separate files for video and audio. this means: when capturing video and audio1/2 this results in having three files on hd; 1 containing the video footage and 2 others containing audio and when only 1 audio channel will be captured, then there is also just 1 audio file on hd. So the problem seems to be that this files can't be used by other apps without having a special import functionalllity. Maybe there is a benefit doing it this way ... maybe a better performance ?? > > So, just another suggestion, why don't you guys install avid on your > > machines to check out some of this features? > > That would mean to boot windows which inflicts physical pain to my spine. > > Cheers, Rolf :-) this means you don't use movie dv any longer? greetings Reinhard
