I tested playing a DVD for the first time today. DVDs play OK using DVD Player but I liked the Front Row user interface better with the Apple remote. Front Row could jump from scene to scene which I wasn’t able to do using iDVD and the remote.
So currently for the best DVD playing experience, either use Front Row or the keyboard with DVD Player.
The sound from EyeTV didn’t mute so both the DVD and TV sound were playing at the same time. There is a setting in EyeTV that fixes this. It mutes the sound when EyeTV is not playing in the foreground.
