Yeah, Memorex are most definitely garbage. You might try to return them cause they were defective and produced a coaster. One of the worst discs made. Verbatim DVD+R DL are the best dual layer discs made, and Taiyo Yuden DVD+R 8X discs [model # (YUDEN000T02) ] are the best single layer discs. Taiyo Yuden makes the best CD-Rs as well. DVD+Rs are better than DVD-Rs. You can get Verbatims on www.newegg.com and Taiyo Yuden on www.supermediastore.com You might be able to find the Verbatims on supermediastore as well.
