I won an Ebay auction for 100 Verbatim DVD+Rs. Normally, these come in retail packaging and actually say Verbatim on each DVD. The two 50 packs the seller sent me don't have either the packaging nor do they say Verbatim. I think I got the old bait & switch scam pulled on me. Before I go postal, I've read that different brands have different grades (ie various Ritek qualities), is it possible these are still Verbatim, but a grade that does not have the lable on them? Is there a way to determine the brand of a DVDR (maybe by the hub serial #?). Please advise.
