Another factor in determining what's "best" is who will be able to play the file. Of the three mentioned above, only H264 is an industry (MPEG) standard not owned/controlled by a single company. It is an open (but not free) standard. AFAIK, it is fully supported on just about every platform, and likely will be for many years to come. The same can not be said for WMV, as we've seen Mac support waning already. -Mike
