Hmm, weird. Either the Wii doesn't like those kind of discs, or you got a bad batch. I've used those discs for years and have had maybe 5 bad burns in that time, and 3 of those were probably my fault.

One other possibility: the writer this user is using. I had a finnicky writer that employed a "bad" write strategy for the MCC codes and it wasn't the disc's fault but rather the burner itself. This is very unusual, most writers have fair to excellent writing strategies nowadays, especially for quality branded media (HP = JUNK, Memorex=JUNK, Imation=JUNK). Verbs or Taiyos are excellent and considered top shelf by videophiles as well as wiihacks.
but the writer is fine, i made backup of other games, using same writer and same verbatim dvd-r. it's just black ops i think
Then try dumping Black Ops again, maybe something got corrupted in the dump, and then burn again. Try a couple different speeds, 2x, 4x, 8x. Hopefully one of them will work.
