I have downloaded, from the Sony website, the driver for the DVD drive and
also the CD drive has the latest driver from liteOn.
As far as inCD is concerned it's not installes on Vista and writing to
DVD-RAM is a bit faster there it's not enough to make a difference.
The speeds I get:
On Vista:
Zipped file to DVD+RW 2.13MB/sec
Folder of files to DVD+RW 0.73MB/sec
Zipped file to DVD+RAM 1.60MB/sec
Folder of files to DVD+RAM 0.89MB/sec
On XP:
Zipped file to DVD+RAM 0.94MB/sec
Folder of files to DVD+RAM 0.64MB/sec
These number are given to show that on Vista even the file copy is not even
half of what it shoud be and is on XP.
Writing to a DVD-RAM is slower on XP than on Vista where it is not what it
should be anyway.
Would these shared IRQ be causing the problem?
Is there any way for me to change then if it a possible cause?
I have foud that the TV app will is extremely choppy,unusably so, when
writing to DVD-RAM.
IRQ 16 NVIDIA GeForce 7600 GS OK
IRQ 16 JMicron JMB36X Controller OK
IRQ 16 Philips SAA713X, Hybrid Capture Device OK
IRQ 21 Standard Enhanced PCI to USB Host Controller OK
IRQ 21 NVIDIA nForce 430/410 Serial ATA Controller OK
IRQ 21 High Definition Audio Controller OK
I am including a partial sys Info hoping it would help.
Thank you for your interst in my problem.

these little turtle, you're right when you say that a 2X DVD-RAM should take
around 1 hour to write a full DVD.

Effectively, if you are truly copying only 800MB, then this is pretty
slow. Are you using the special DVD-RAM that often comes with these
burners or if you are using the default driver from WinXP?
I remember that the last time that I've installed a DVD+RW/DVD-RAM
recorder, the driver for DVD-RAM was not installed by default when running
the setup disk: it was a separate option in the setup menu and it was not
activated by default.
It's also possible that some packet driving software like InCD from Nero
might interfere. This could be particularly true if the setup disk for
this recorder comes with its own packet driving software or if you have
installed more than one of these little pests.

The copy that takes 3 minutes is at 4X to DVD+RW
Writing at 3X to the DVD-RAM then should tke 3x3/4 or 2:15 minutes even
if
you double that to account for the verify you still get aroud 5 minutes
which
is al lot less than 36 minutes.
If it takes 38 minutes to write 800MB it would take 3 hours and 45
minutes
to fill a DVD. I don't think anyone would consider that acceptable.
Even at 1X which is 1.32MB/sec it should take just under 1 hour to write
a
full DVD.
It makes one wonder what kind of programmed delay timer is written into
the
program that controls the write to DVD-RAM on XP and to DVD+RW and -RW on
Vista.

Even if your sony can burn DVD-RAM at 12X, the fact that you are using
3X
means that you are limited to 3X. Furthermore, for DVD-RAM, you must
divide
the speed by two because each writing is verified with a reading.
If you are burning your folder in 3 minutes at 18X, then we have 3m *
18x/1.5x = 36 minutes; pretty much the time that you got.

I have a Sony DRU-830A rated at 12X for DVD-RAM on an Intel Core2 Duo
running
Windows XP and I use dvd-ram media rated at 3X. I should expect to
copy an
800MB folder in about 4 minutes or less but it takes 38 minutes. That
is
very
consistant. Getting rid of CD recording didn't help.
Copying that same folder to a DVD+RW takes about 3 minutes.
I also have Vista an it doesn't take that long on Vista but the speed
is
still not what it should be. On Vista writing to a DVD+RW take 5
times as
long as it does on XP. There that folder would take about 15 minutes
to
copy
to a DVD+RW disc.
I wonder if anyone else is having speed problems with DVD-RAM speed on
XP
and/or DVD writing speed problems on Vista.
I would appreciate any help.
