[delthas]

The project currently supports MPEG 1 files only.

@delthas I have folowing file: error.zip, which doesn't play with JavaMP3, but plays with any other audio player. The error message is:

Any plans on adding MPEG 2/2.5 support? If not do you know of any website that explain the difference in encoding as all I've found is information about the bitrate and that mpeg 2 was created primarily for TV/DVD/Video or something like that.
