Just got back from one of our Best Buy Stores with 1-50 pack of DVD+Rs 16x. The label says 'Made in Talwan' DVDInfoPro says they are 'Sony D21'. Are these Good, Bad or Trash? I hate to use these as System Recovery Discs if they are crap but we ran short and our order isn't to come for another 2 or 3 days. As always... Thanks for all your help!
