windows wont recognize dvd ram

[Parker]

Hello All,
I have a Hitachi DVD Camcorder that formats the dvdram discs to create vro
files. I have 1 dvdrom drive and 1 dvd writer. This disc is not able to be
read in either drive. Nero toolkit says that the dvdrom is able to do so.
Windows explorer does recognize that a disc is in but wont show any files.
I'd like to copy them onto the HDD and then use VideoRedo and my authoring
software to create a DVD but I have no way to copy this file from the dvd
ram disc. I have XP pro and sp2 with all updates asus mobo 2.6 ghz
processor 1gig ram. Both of these drives will play back any DVD. Any ideas
where to look for this problem?

Thanks

You need a DVD drive that specifically reads RAM disks. What DVD optical
drives do you have in your PC?

Hi Cari,
I have a Samsung DVDrom that according to the NeroTool can read dvdram
discs. The other is an Nec cd/dvd writer which I have 2. One in this
machine and 1 in another which does read the dvdram discs even tho the
Nerotool says its not supposed to.
Thanks for the response

Check at the Samsung website....

I check it out and see if there is anything on there site that can correct
this problem. I also was checking into the udfs.sys file that may have
caused this problem. Im not completely sure if this HotFix from microsoft
is the cure. I'll check back after I get the model number and let you konw
the outcome.

Thank You

I recently bought a Toshiba RD-XS24 DVD-Recorder. It has a huge HDD but
I'm mainly interested in transfering the recorded videos to my
computer, so I started recording on DVD-RW and DVD-RAM discs in VR
mode, but my system (Windows XP SP1) wouldn't "see" anything at all.
Microsoft has a HotFix (KB818733), but there is no direct dowload, so I
looked for the files udfs.sys and cdfs.sys on the Internet and finally
found them on eDonkey (version 5.1.2600.2180 for both of them). I
replaced the original udfs.sys and cdfs.sys
(C:\WINDOWS\system32\drivers & C:\WINDOWS\ServicePackFiles\i386) with
the ones I dowloaded and the problem was immediately solved. Now, my
system sees the VRO (mpeg-2) video files and I can copy them easily.
When replacing the .sys files Windows will warn you against doing so,
but ignore the warning (you should keep the originals renamed just in
case something goes wrong). One last thing: DVD-RW discs must be
finalized before been extracted from the DVD-Recorder (finalization can
be cancelled afterwards if you want to continue recording on the same
DVD-RW or you can format it - DVD-RAM discs are O.K.)

Thanks Jason, I'll give that a go!!

I do have 1 question about replacing these files Jason. Did you overwrite
the files or delete them and copy the new one? If I delete the file it
replicates itself within a few seconds.

I followed the procedure I'm about to explain for one file at a time
(i.e. I made four separate replacements), let's take udfs.sys as an
example: I went into the directory C:\WINDOWS\system32\drivers and
renamed udfs.sys as udfs.sys.bak. A couple of seconds later Windows
warned me that important files of the system had been replaced, asking
permission to restore the original files. I said no, so udfs.sys.bak
remained. Then I copied the new udfs.sys into the directory and a
couple of seconds later Windows issued the same warning and I said no
again, so the new udfs.sys remained. Exactly the same went for
cdfs.sys, so now in the directory C:\WINDOWS\system32\drivers I have
the new and the old files. There were no warnings when I renamed and
replaced the files in the directory C:\WINDOWS\ServicePackFiles\i386
(which is a backup-directory ). My system could see the VRO files soon
afterwards, without any need to reboot.
I hope it will be as easy for you to do it as it was for me. However,
if your problem persists, then first replace the backup files so that
Windows will not have alternatives!

Is there somewhere that I can turn off the automatic replacement. Mine did
not ask me it just replaced it. Im have sp 2 installed.

After I posted the message I thought that you might have SP2 installed
and unfortunately that's how it is (just to avoid such problems I've
never installed SP2 and I have not regretted it). However, there may be
a way out of this by booting the system from a CD and replacing the
files while you are under the CD's O.S. and that's what I did once when
I had similar problems. Make a bootable CD by following the
instruction contained here: http://www.nu2.nu/pebuilder/ (Bart's
Preinstalled Environment). If you still can't replace the files, then
make the bootable CD from a computer with SP2 not installed, which will
bring the system to the status of mine (only SP1). You can use a CD-RW
to avoid wasting a CD-R.
