DVDs not recognized
I have two DVD drives, a Piooeer Read only, and a Lite-on + or - RW. Neither
of them recognizes DVDs, either movies, or homemade DVDs or blanks. They
both read CDs without any problem.
I have WXP SP2, and have installed Power DVD 8, and tried to see the DVDs
with that program. No luck.
I suspect I have some kind of software issue, but don't know how to fix it.
Can somebody give me some advice before I go out and buy new drives?

Re: DVDs not recognized
Thanks for your response, but it has gotten me in a peck of trouble.
Even though the symptoms listed were not exactly the same as mine, I altered
the registry as suggested.
The problem is that there are multiple instances of 10318 keys and Upper and
LowerFilters, and I deleted them all, including those for keyboard and mouse.
Now I cannot access my system at all.
Yes, it was stupid.
How can I recover from this? My system won't come up in Safe Mode, and I
can't get to Restore. To compound my problem, I don't have a recovery disk
and can't find my XP disc.
I can order another, but will the CD drive read it?

You mean you "changed" the registry without *backing up the file*?

Sure this is OS independent. You could also stick in a "Linux rescue
CD" and use a usb-drive or another HDD in the System to *BACK UP
your valuable Data just to be on the *safe* side.

If I had a vfat USB-HDD big enough to hold c:\

Use a System rescue CD.
After the bootpocess finishes it will give some sort of shell.

On the one I have in mind it gives a few instruction among
them one on how to load the driver for the XP file-system.

After that is done,

create a folder
"mkdir /win-os"
"mount -t auto /dev/hda1 /win-os"
(assuming window is on the first HDD)

plug in a usb-drive, and create also a folder for it

"mkdir /usb-drive"

"mount -t auto /dev/sdc1 /usb-drive"
(usb-drives are seen as SCSI so that's why its not /dev/hdb1)

copy the whole system to the usb-drive

"cp -a /win-os /usb-drive"

This process will not create a bootable OS you can use, BUT IT can
help you to salvage the Data on the Disc if you're not able to
rescue the installed OS.

Hopefully a "restore" with MS tools will solve the problem though.
