Don’t know if this is the right place to post, but I think it is.
Anyway, I have a 1640 and so far, all my burns have been good, quality scores of 90-99 on my media which is usually Ricoh 8x or 16x and DVision Taiyo Yuden 8x, all DVD+R. So far, those have all been in ISO format.
Recently, I burnt some discs in UDF format because of some large files. I notice that with all those UDF format discs, a quality scan will usually drop quick to 96, stay steady, then midway through, it will plummet from 96 to 79 and that will be the final score. It’s the same for both the UDF discs I burnt.
Is this normal?
