I've been looking at buying some super cheap media such as Supermedia store brand or Power Matrix for backing up my daughter's cartoons. She's 3 and can operate the dvd player without any damage, but she's hard on the discs. Does anyone know of some super cheap media I can use as a "throwaway" backup, rather than having to waste a good TY or Ritek disc? Also, does anyone know (or have a guess)on what the coaster percentage is for the cheaper media? If it's under the 20% range that would be ok.
