Hey Charlie......advice

There is no table. Most manufacturers don't publish the data but quietly imply that they conform with the 45% - 85% reflectivity range specified by the international standard for a DVD drive to be able to read.

In fact we are only guessing that cheap media falls below this range because there is evidence in the difficulty some people have with the media. It could just as well be a crap dye in the individual disk or even the batch so that the burner thinks it's done a good job but the result is either a poorly defined opaque mark or an optically poor disk as a whole.

I'll be posting some more informationon this class of topic very shortly.
