Clearly you didn't do your homework. Mini Discs are a

I have much experience with MD, as it was the only format I used for years before switching to my iPod. Original MDs used what is essentially MP2 technology which left the listener with poor sound quality. Later developments from Sony allowed for better compression and clearer sound.
Although NetMDs have a USB connection Sony uses proprietary software to re-encode your music an transfer it to your MD. Sony also limits your ability to rip the MD once you have recorded it. ITunes is only incapable of reading an MD due to the fact that you require proprietary sony software.
Interesting that you mention that iTunes will not work with anything but iPod. Again, do your research first. iTunes will mount certain Creative players and even mounts my Palm allowing me to sync music to it from iTunes itself. iTunes protected music from iTMS does not work obviously, but anything I have encoded does.
Obviously you also missed the point of my post. MDs are encoded in a format that is essentially lower than that of a Variable-rate MP3 or an AAC file. Especially if you are one of the many people who have set their ATRAC3 capable MD to record at the highest level of compression. It is better to go back to the original source and re-encode rather than attempt to pull low sample rate audio off of an MD. It is also much easier.
If you do know of a way of ripping music off an MD it would be much more constructive to let Emily know what it is rather than posting an uninformed rant aimed at another poster. This forum is for constructive support and advice not a place to air personal grudges.
Take care.
