Bit of an issue here, Windows 7 Home Premium 64bit - Samsung DVD R/W and
LITEON IHOS104-37 BLU-RAY player.

Both show up in device manager as working properly but cannot read
DVD/CD at all from the Samsung and can only read slowly & intermittently
from the LiteOn. BIOS sees them both as there and ok.

I've tried all the 'fixes' I have found on the net (registry hack,
upgrading mobo files, bcdedit.exe fix, etc.) but it is still not playing
properly.

The strange thing is I can watch Blu-ray movies through PowerDVD 8 BD
and I can also use the LiteOn to rip CDs with Ashampoo Music Studio 3.

It's bl00dy annoying that they don't work as normal and so far nobody
(Microsoft nor the manufacturers) has issued a fix for it despite many
other cases on the net.

Anybody here have the same issues and more importantly is there a fix?

In the interim I have installed an IDE DVD R/W drive and it works perfectly.

Cheers

Kol

At first it sounds like a driver issue but that should have stopped PoweeDVD
and Ashampoo too.
I wonder if the problem is missing codec's rather than a driver problem.

A possible shot in the dark... The two programs that do work most likely
supply their own codec files for the file types they support.

You might try downloading the Codec files at http://www.codecguide.com/ and
see if they fix your problem. I notice they advise those using the 64-bit
windows codec's to also install the 32-bit to support any 32-bit software
you might decide to run at some time.

If hard drive space is not an issue you might try the mega pack. You should
be able to tell the install program not to install the music players if you
don't want them when the question comes up.

Well, I finally took the easy option and installed an IDE DVD R/W drive
which works perfectly.

Microsoft help centre were going through a straw grasping exercise of
try this, try that but all to no avail - good of them to attempt to
resolve it. I believe the cdrom.sys file has been rewritten for windows
7 and it doesn't encompass all SATA drives....
