AARON I have the EyeTV 500 and it's incredible. HDTV broadcasts look spectacular. The system requirements state a dual G5 for the highest-resolution broadcasts (1920x1080 aka 1080i), but my PowerBook G4 1.25GHz has no problem with it either since the 1.5 upgrade.
Now, with the 1.6.3 upgrade, channel switching is smoother, no audio studdering after changing the channel, and performance appears to be improved yet again.
Great job, guys!!!!!
