Sony DVD+R 8x
The Sony DVD+R doesn’t meet the ECMA requirements as the maximum of PI Errors exceeds the permissible limit. The final section of the disc is especially poor in this respect.
Verbatim DVD+R 16x
The Verbatim DVD+R isn’t blameless from the ECMA standpoint as there is a spike of PI Failures above the allowable maximum. The burn quality degenerates at the end of the disc.
Digitex DVD-R 16x
The Digitex DVD-R cannot be criticized as the level of errors of both types fits within the ECMA requirements. The errors are also quite evenly distributed along the disc.
LG DVD-R 16x
This DVD-R disc from LG is recorded with excellent quality, in full compliance with the ECMA requirements for both types of errors. The errors are very uniformly distributed along the surface of the disc.
