IIRC, both Quicktime and WMV can use any one of several video codecs. For example, the video in a given Quicktime movie may be compressed using an mpg1,2 or 4 , H.264, motion JPEG or a host of other compression schemes. The big difference is that Apple is pushing industry standard codecs (mpg1-4) while MS is trying to push its own proprietary format as the codec of choice. Just saying the above because many people seem to think Apple is using and pushing proprietary codecs, when in fact they are the ones pushing the codecs endorsed by the Motion Picture Working Group (that doesn't sound quite right) -the mpg standards (mpg1 used in VCDs, mpg2 used in DVDs, mpg4 to be used for HD DVD's). At this point, Real and Microsoft are the only ones pushing a non- industry standard. -Mike
