Another EAC3to GUI

AEAC is an easy to use front end that uses many of the core tools available (such as eac3to, MKVToolnix, etc…) to create an mkv from either a Blu Ray or HD DVD disc.

No encoding is done , so you are left with a perfect 1:1 copy of the original disc. You can keep the original HD Audio track, only the core audio track, or even have the audio track converted to FLAC.
