Hi and welcome back! Hopefully it will be easier to stick with it this time around...the forum has really helped me stay consistent so hopefully it will do the same for you.
I'm not sure about formatting for your iPhone (I've wondered that too but keep forgetting to ask)...but I do remember reading somewhere on the site that converting the format can diminish the quality of the track and cause it to lose some of the background little bits of sound that are so finely tuned an integrated. But I don't know a lot about format conversions so hopefully an admin will chime in and correct me in some way...would LOVE to use my iPhone for this.
So just to clarify, if you're planning on using QuickTime to listen do you have a CD drive on your mac? If so then that should work perfectly! I always listen to it on my pc because my favorite headset connects through a USB. I just pop the CD in, play it through Windows Media Player (I don't see any reason why any other player would be any different), sit on the couch and enjoy!
Another possibility...and considering you got BrainEv long ago it might be a long shot...but do you still have the original email you got when you purchased the program? Not sure if they even did this from the beginning, but currently they email you a link to audio tracks that you can listen to as well. It's supposed to be somewhat inferior to the CD but better than nothing. So maybe scour your email and see if you have something like that from way back when? But if you have the CD and a drive in your mac then that's prob your best (and highest quality) method. Good luck!
