You can also burn tons of CD quality 16/44.1 files on a DVD-A. Never burn an audio CD again! Well, maybe for the car. You can also make mixed DVD-As, with 24/96, 24/48 and 16/44.1 files on the same disc (as well as other resolutions). There can be up to 9 different groups on a DVD-A, and each one can use a different resolution of files.
