Grand Theft Auto 4 (GTA 4)
I tried your process and it didn't seem to work, unfortunately.
I guess I need to re-rip my old CDs into MP3s instead of M4As.
I use it to batch convert WMVs to AVI so they'll play on my portable DVD player, but it also converts audio files too.
Might be worth a try - all you do it drag and drop all the files you want to convert and it'll do it all for you. Even I can use it and I'm an idiot when it comes to this kind of thing
