I've been using AVC for several years and it has allowed me to do several things that I have found very useful. I mainly use it to download youtube files such as movies, documentaries, and music. Being an audiophile I also generally keep my music content in a lossless format such as FLAC in order to get the best audio reproduction possible and AVC converts files like MP3's as well as taking the audio portion from music videos that often times are in WEBM format when I originally download them and since I generally use AVC to download them it's very convenient in the fact that they are already in AVC therefore a simple click is all it takes to quickly convert the audio portion while, if I so choose discarding the video portion. I most definitely recommend AVC.
