I had issues with my Sega CD model 1.
The music stop and the drawer open, sometimes in very beginning, sometimes in first minutes in the game.
It's weird because I just changed caps and cd laser unit (KSS 240 A with 12 tracks in oscilator board)!!
Everything runs fine but this enhanced disc (and your CDR-r copy) doesn't....
Any suggeetion?
