If you only intend to watch movies, then a combination of FreeVCD and Basic will be fine. Changing the Apple drivers with the one's from Intech fixes playback on Macs regardless of the player used. I've heard in the past weeks various quality results from different movies and player combinations. The consensus is that Quicktime Basic or Pro v4.1 is the hands down best player in terms of picture quality. A lot of the quality does come from the VCD disks.
Corrupt disks can be common and one's processor and video speeds affect which is the best player.
We recommend using Quicktime from Apple. It's included in every Mac system for free. There is also a third party software we like called FreeVCD . We recommend Quicktime over FreeVCD because it does allow you to reside to a smaller window, important if you are using a slower machine to play movies. With the need to purchase Speedtools, The money would be better off saved for the essential Intech product.
