^^^^^ It wasn't my intention. I should have written "avoid using
such words as "mysteriously" *alone* in reports," as that's what I
meant. The fact that no errors were shown or logged is indeed
mysterious, but reassurance that this is actually the case is absolutely
essential.

If you burn a lot, you might as well choose to modify code to
effectively convert the error to a warning (as mentioned in the referred
post).

There was only one dvd+rw-mediainfo output, for blank media, right after
"Failed to change write speed" in originating post. Was it it? If media
remained blank, then you might be able to re-use it... Note that the
question essentially was "I *would* *like* to see," so if you can't spot
that particular media, just drop the question. A.
