NEC ND2500 cd-r reading problems

Hi i got some pretty big problems using blank cd-r’s from Imation. Everytime i try and use these cd-r’s the computer almost freezes until i eject the disc and things turn back to normal. This stuff doesn’t happen with normal written cd-r’s, from any brand (like mmore, lifetec and also imation). When i try and insert a dvd instead, everything works fine, the empty disc is being recognized and i ready to be written onto…

What could be wrong here? I use de NEC nd2500 with the latest firmware. I tried and look for a compatibility list but i don’;t see anything special there…

Anybody’s got a suggestion?
