> this verbatim 2x dvd-r didn't work with 5.16.4.8.5: You've got to work on your reports:-) As it was not trivial to correlate the sequence of [failing] commands and conclusions you make:-) Starting with this first line. You say "this media didn't work with 5.16:" and after ":" present perfectly sane mediainfo output. You surely mean that 5.16 failed to record media *similar* to one you've recorded earlier with 5.13, but then you should say just that. "This media didn't work:" means "this is the very disc which didn't work," which was very confusing. Note that dvd+rw-tools page explicitly say "attach mediainfo for *resulting* recording." But enough whining:-) Let's assume that this is mediainfo output for *previously* recorded media of same brand...

This was brought up in http://lists.debian.org/cdwrite/2003/cdwrite-200312/msg00159.html and discussed in follow-ups. Unfortunately I can't assert that consensus was reached there. The problem reportedly disappeared with kernel upgrade, which I couldn't really accept as real explanation for the phenomena. So far the failure is/believed to be "accounted" to some kind of automounting facility, but it feels that it *might* turn out to be a BTC-specific problem and a closer look might be required. So bear with me... > looping until process killing. > I burned a 4x verbatim dvd-r with the same command line (growisofs -Z > /dev/dvdrw -V TITLE -dvd-video ./) with 5.16.4.8.5 succesfully, Does it mean that you can *reliably* reproduce the failure with 5.16 without -dvd-video option?

This means that write-once media will be mastered as non-appendable. The latter is surely explanation for the differences in mediainfo outputs. First output shows appendable media, second one - closed directly after first session. Indeed (below is interleaved output): > READ DISC INFORMATION: > Disc status: appendable > Disc status: complete > ... > READ TRACK INFORMATION[#2]: > Track State: invisible incremental > [not present in second output as disc is closed] Both outputs are perfectly sane otherwise.
