So the disc is not (yet) a coaster after all, eh?

OK, I just tried rerunning growisofs again on the same media, twice.
It failed in exactly the same way, and dvd+rw-mediainfo gives the same
information as the above, nothing changes.

OK, this is wierd, I tried -speed=6 and -speed=4 but
growisofs kept saying the "Current Write Speed is 8.2x".
# growisofs -speed=6 -dvd-compat -Z /dev/hdc=/tmp/tj1-60.iso
Executing 'builtin_dd if=/tmp/tj1-60.iso of=/dev/hdc obs=32k seek=0'
/dev/hdc: "Current Write Speed" is 8.2x1385KBps.

But when I tried -speed=1 then growisofs said "Current Write Speed" is
4.1 and it worked!! ...for a while. (Keep reading).

Different SK error code now: 04/09/01. I could mount the disc, and see
the list of files, but the files are not readable. The kernel gave
these messages when I tried to read the contents of the files:
...
attempt to access beyond end of device
hdc: rw=0, want=8951444, limit=6863360
Buffer I/O error on device hdc, logical block 2237860

Argh! This is driving me nuts. I will try different brands and types
(DVD+R, DVD+RW, DVD-RW) as soon as I get a chance to buy them, and I
will also upgrade the firmware to the latest official version from LG,
then I will report back here.
One question: why did -speed=N not give Nx, but something different?
Thank you so much for replying and for your suggestions, Andy.
