You'll need a CD in your drive to have the "Detect Read Features..." button to actually do something other than just bring up a new window with an OK button. If you did that and "Accurate Stream" doesn't show up, then sadly, your drive doesn't support that feature.
As for the CD you burned through iTunes, if it plays on a regular CD or DVD player or if you "Open" the CD through Windows Explorer and the file(s) show up as Track01.cda, Track02.cda... then EAC should be able to rip the music into a WAV file.
If you are having problems with burning the song to a CD via iTunes, read my post in this thread: http://www.animemusicvideos.org/phpBB/viewtopic.php?t=79414
If all that fails, then try QTFairUse (http://www.hymn-project.org/
). It can decrypt the m4p file which then can be converted to a WAV using Winamp (http://www.winamp.com
BTW, here's an easier way to do audio conversion with a current version of Winamp (5.32 or newer) without going into the Preferences and mucking with settings and plug-ins:
1. Open the audio file you wish to convert or add it into Winamp's Playlist Editor.
2. Right click on the song in the Playlist Editor to bring up the option menu.
3. Select Send to:
, then Format Converter
4. Choose the folder you wish to save your new file and how you want it named.
5. Select under Encoding Format
, WAV Encoder v1.01
6. Click OK
