Hello all..

This may seem like a really strange problem.. but I cannot burn DVD any slower than 4X.

growisofs -Z /dev/dvd=/blz/DVD/DVD2/doar.img -use-the-force-luke=notray -use-the-force-luke=tty -use-the-force-luke=dummy -use-the-force-luke=dao -dvd-compat -speed=1

/dev/dvd: engaging DVD-R DAO upon user request...
/dev/dvd: reserving 132592 block, warning for short DAO recording
/dev/dvd: "Current Write Speed" is 4.1x1385KBps.


with -speed 8

/dev/dvd: engaging DVD-R DAO upon user request...
/dev/dvd: reserving 132592 block, warning for short DAO recording
/dev/dvd: "Current Write Speed" is 8.2x1385KBps.

The DVD i'm trying to make compatible with my stand alone DVD players..

at 6x it worked with neither..
at 4x it worked with one of them...

So, Idealy I would like to burn at either 1x or 2x...but any speed I put in lower than 4x just ends up burning @ 4x.

The same happens if I use K3B.

Any suggestions appreciated...

That's probably normal. Not every burner is able to burn at slower speeds. If your DVD players have trouble reading, it's usually mainly the media that causes the problem. Buy a test pack or something with media from different manufacturers and test out what works best with your players.

Alternatively, if you suspect a problem with growisofs, you could try using cdrecord-prodvd instead. Although I personally use growisofs and have no such problems.

I have the same problem only my drive won't burn at lower than 1x with K3B, but if I reboot to *gag* Windows and use Nero, the drive will happily burn at 1x.

I was having a lot of speed problems with a pioneer dvr 108. After I upgraded the firmware, I got all the correct speeds.

Hi,

I tried to ask the same question at various places, but no satisfactory reply yet. I think it is nature to play it safe by burning media at slower speed, especially DVD. Why there is no such option (yet)?

I even give Nero Linux 2.000.6 a try. I also *have to* burn DVD at maximum speed with it. Can anybody help? Thanks.

I just replaced my 4X dvd burner with a 16X one, but can't burn my DVD any
more. I was cautious enough to burn my first trial with lower speed, but
growisofs wouldn't allowed me. It still burns at 8X, thus produced a
coaster at the end:

I used "-speed=4", why it didn't work?
Why the growisofs insists to use speed 8 even after I specified "speed 4"?
Is there any way to burn my dvd at a lower speed?

thanks

PS.

- The DVD media was perfectly fine with my previous (no
longer available) burner.

- The load was around 0.1 when burning and I used "nice -n -2". So it is
not a system load issue.

- I tried a second time, the load was still around 0.1 when burning and I
still used "nice -n -2". but got another coaster:
