Hello again,

So, I looked at the two logs attached on the arch bug report.
Unfortunately the 161-1 log file was done without a medium in the
drive (or you did it too early and the drive didn't finish reading the
disk yet). Can you please re-do the 161-1 log?

But while I looked through the code, I noticed a flaw in the "DVD-RW
ro/seq" patch [1]: It inserts the ro/seq differentiation into
feature_profiles(), but this should just detect the drive
capabilities, not the medium state.  I fixed that in [2], but I
suppose this is not the complete fix for that bug yet, since it didn't
break DVD-ROM operations at all, it just falsely claimed that they
were rewritable.

Thanks,

Martin
