I just received the TY discs I got from supermediastore.com on sale for 36 bucks for 100. the thing is I am having errors, nero won't verify every copy. i have had to throw away a bunch. i haven't watched them but they fail verification. are all TY disc genuine TY? believe it or not, the only discs that worked 100% of the time were office depot discs. i know that is strange. any thoughts, should i ignore the verification thing?
