mpeg1 is available natively on PCs and Quicktime is more obviuosly associated with Macs.
Both these formats are widely availabe to both platforms and so although not necessarily the best quality (in the case of mpeg1) they are the widest supported.
DivX and such are realtive newcomers and are definately not as widely dfistributed - MPEG 1 became standard on pc's from Win '95 Active Movie days onwards.
MP4 and AVC are widely available for the portable formats.
