[Dvdrtools-users] Writing DVD+R with Philips DVDRW228

[Mark Blanchard]

I need to write DVD-ROM compatible disks using the new Philips DVDRW228 
DVD+R(W) drive.  I'm using mkisofs to build the disk image and then dvdrecord 
to write the image.  However, the resulting disks are only readable in the 
Philips drive, not in standard DVD-ROMs (e.g. LG DRN 8080, which should be 
compatible with DVD+R disks).  I've checked via google, but cannot find any 
information to help me, hence this message.

The disk image was made using 

        mkisofs -R -o /tmp/dvdimage.iso /data

and is around 1.2GB.  I've verified it using both isoinfo and mount.

I then used

        dvdrecord -v -overburn speed=1 dev=0,0 -data /tmp/dvdrecord.iso

I found I had to specify -overburn before dvdrecord would accept the size of 
the image file.  Without -overburn, dvdrecord exits without burning the image.

The (reconstructed) output from dvdrecord is:

******************************************

There are two things here that concern me, and I'd be grateful if someone 
could help me out.

First, the Philips drive is treated as a CD-R, which I guess explains the 
need to use -overburn.  Is a device identifier available for DVD+R in 
dvdrecord, so that the size of the media is treated correctly?

Second, could the fixation error cause the disk not to work in a DVD-ROM 
drive?  I get the message "no medium detected" when I try to mount the disk 
under linux, and a similar message using MS Windows.

Another point of confusion: regardless of the speed setting (I've tried 0, 1, 
2 & 4), dvdrecord always claims to record at speed 11.  Can anyone explain 
this to me?

Many thanks for any help,

Mark
