According to a DigiTimes reporter quoting "industry sources"; media that are in reality, 8x and 4x DVD+R/-R discs, are now being passed off as 16x and 8x respectively and the problem seems to be on the increase.
As demand for 16x DVD+R/-R discs grows with the increasing use of 16x and 18x DVD burners, some makers have mislabeled their discs with higher speeds in order to grab profits, the sources pointed out, noting that there have been reported cases of counterfeited TDK 8x and 16x DVD+R/-R discs made by small makers in Taiwan.
