As much as I understand copyright, intellectual property etc etc, I should be able to play my audio books on whatever device I so choose, not just on ‘approved devices’.
I have a few programs that ‘convinces’ a certain format to play on a generic MP3 player. But there’s always a catch. The problem is it makes it into a bunch of 7 minute MP3 files, so instead of 3 part “Approved device” format, I have 70 some odd mp3 files. So, I have to get an MP3 joining program to make “Part One” etc etc.
