Re: Help with DVD+RW w/UDF file system

I have been trying to get DVD+RW w/UDF to work under Fedora Core 3
[Kernel  2.6.12-1.1372_FC3] using a Samsung TS-H552U DVD drive.
I have formatted the disk, I have put a UDF file system on the disk, and
I have removed it from the automounter.

I can copy small files [<1mb] to the disk fine.  I can 'rm' the files
fine.  However when copying large [>1gb] files to the DVD is painfully
slow, and the load average on my Athalon system jumps to 3.87 or higher.
The intention was to use the 4.3 Gb of DVD space as archive for my
flexbackup files of my home systems however this may be too slow.

Any thoughts as to what I am doing wrong here?

Is all the time system? Does hdparm show the drive as DMA enabled? If it is running uning PIO it will take a great deal of CPU.
