Can someone tell me the difference(if any) between the TY Silver Thermal DVD+R and the TY Silver Matte DVD-R when it comes to burning quality and compatibilty playing in dvd players! I just bought 2 100 packs of the Silver Matte's from supermediastore.com and didn't realize they were different other then being +r and -r and that the silver thermal burns at 8X. This is my first purchase of the TY's and hope there isn't any real differences between the two! Is the quality expected to be the same? Any info. would be helpful! Thanks!
