DetailsWhen trying to play certain AAC/mp4 fles Rockbox will hang or become extremely sluggish, usually resulting in a necessary reboot. In all but on occassion, the audio stream hasn't begun.

This task depends upon
The first file (002) works fine on my Sansa e200, but the second one doesn't play at all. This is a known problem, where long MP4/AAC files will not play at all or possibly crash Rockbox. The reason is that the decoder runs out of memory, because it doesn't handle some data tables needed for playback and seeking in a very efficient manner (it pretty much reads the tables verbatim from the file).
