Re: dvd+rw-tools update [6.0, DVD-R DL]
Hi,
i nearly gave up the hope to see more growisofs releases.
The release of version 6.0 is good news.

I recently introduced a fifo into my growisofs script.
Now it is already obsolete. What a carreer. :))
6.0 seems to run fine here.
My fifo keeps your RBU at 100% or 99.9%. :))
top reports growisofs gained 32 MB of weight. (The difference
between RBU 92.2% and RBU 37.0% is 18513920. That matches.)
Isn't 32 MB a bit greedy as default buffer size ? (It is a
size with good performance, as i know.)
Would it be possible to get a ring buffer size option ?
About -use-the-force-luke=noopc :
I lost a dozen DVD-RW meanwhile with
:-[ PERFORM OPC failed with SK=3h/ASC=73h/ACQ=03h]: Input/output error
Will they get a new life by this option ?
Can you tell me something about your motivation to introduce it ?
> - [artificial] version harmonization;-)
What about -use-the-force-luke=noload ?
Does it work now ?
No, it doesn't. :(
Is there still the old reason not to leave the tray in
after writing under any circumstances ?
If not: since what version of growisofs is it possible
to risk the tray staying in and somebody reading from the
DVD. (I remember some ugly freezes 3 years ago. You then
introduced the in-out ballet of the tray.)
> As for DVD-R DL. I've got quite discouraging results when testing
Some reports about experiences and recommendable growisofs
options for DL media would be welcome. I received some questions
about DL from my users recently and could only point to the changelist
in growisofs.c 5.21.
Have a nice day :)
Thomas
