Burning 360 Back-ups and (no reference point found)

[emerica]

I have burned over 50 xbox 360 back-ups using verbatim DVD-DL cds and have had minimal problems (a few coasters here and there). But now i am having a problem. My computer was out of service for awhile being repaired so i just got it back and had no more verbatim so i just got a pack of memorex because it was all i could find at the time and for some reason i get this message. Device not ready (no reference point found). I dont know if its the cds or my drive that just cant read them or what. I put in one of my other back-up and it read just fine and said the disk is not empty obviously because it was used but it could still read it. Here is the log any help would be appreciated.
