Hopefully they had it sorted by then.

Thats not far off the mark for a full 4.4GB+ CAV burn and
about right if you are burning less than 4.4GB.

Another Debian user? I use Wodim (cdrecord fork) for CD burning.

Sorry! I misled you about the read speed for 3x DVD-RAM in
my Liteon LH-18A1P. The numbers I quoted were for a partial
read. I have since read a full DVD-RAM and discovered that
the Liteon uses a P-CAV strategy for reading DVD-RAM. It
starts at about 3x and increases gradually until it reaches
5x at around 1.6GB, the rest of the disc is read at 5x.
Average for the full read is 4.6x

You're very welcome. I'm glad we made some progress with
it.
