Thanks for posting this. Because of your post I downloaded and tried it. Pretty nice.
A note about what I do differently than the way the help video demonstrates (I'm using a windows machine).
BTW, I do this because my car will play itunes from a memory stick. I like to load up the memory stick with itunes rather than wav files to save space. Unfortunately, the car does not seem to read the song title itunes data. It needs each music file to have a name in order to display the song title on the stereo readout.
The following may seem like a real hassle but doing my own conversions in the past took me many more steps and more time and effort.
Rather than the default folder in the user profile, I keep all my itunes music in a folder that I keep elsewhere just as with any other data folders.
In boottunes, I changed the destination path so it looks something like C:\data\itunes
After boottunes does the conversion, I'll now have a folder path that looks something like C:\data\itunes\e5h*5hyl9yyc#
I simply rename the folder.
The conversion names the song files 0.m4a, 1.m4a, etc. Now I just rename each file to the song name with numbers "01 tuning, 02 Bottle Up and Go" etc.
Final step, open itunes and add the folder to the library.
I put the numbers on the song filenames so the car knows how to sort properly. Otherwise it goes by alphabetical order.
Oh, finally FYI - itunes get info shows that the files are 16/44.1 at 702 kbs
