The EyeTV is a remarkable device in more ways than one, but it is slightly limited in its function. Initially, the appeal is very great: It's sleek, easy to use, and looks great next to any Macintosh computer. The downside, however, is that if you're looking for the most versatile Mac video capture card, you may have to go elsewhere. EyeTV is a great piece of equipment that allows you to watch, record, and stream satellite and cable television directly on your computer without hassle and without too many cords. This is a huge upside if you're looking to record only television shows and movies that are played via your cable/satellite TV provider, but unfortunately that's where EyeTV's functionality essentially ends.
The issue is that, while you can do all of the aforementioned things, you can't record from a DVD player, VHS player, game console, or any other device that isn't your television network provider. This is a pro and a con, of course, because it's extremely easy to record TV shows, but it is indeed at the loss of the ability to record from other devices.
If you just want to record television shows, though, there's no better alternative.
