I use this on a MacMini Core Duo that is connnected to my entertainment center.

The recent update causes problems with auido playback by other programs (iTunes, Movies via front row, DVD player app, etc).

For example, I like to listen to iTunes tracks in the evening while cooking dinner. If EYETV opens to record a prime time show, iTunes will suddenly stop working -song stops playing and can't restart wihtout several adjustments to Midi Audio in Utility folder, etc.

EYEtv needs to play nicely with Apple's bundled apps.

I sent feedback directly to el gato asking that they address the problem.

Once they get this probelm fixed, I'd give it 4.5 stars. If they allow for Season Pass recording... it'll get 5 stars. Good product overall, but this is a serious problem.
