I was looking at pricing on SD cards and I wondered why Ultra memory cards cost $7.99 while while other cards cost $15 dollars or more. I noticed that the ULTRA cards didn't have content protection (CPRM) and some of the cards that do cost more. I asked around on other boards what the difference is and they say that I'm paying for the copy protection or a license to protect the digital rights of others and that it should work just as good except that it won't have copy protection.
