DVD and Audio Cd not recognized. Why?

Tuesday Morn

(Complete description of problem at bottom.)

I got the DVD working by using the 3rd solution on this page:
http://www.comsoc.org/livepubs/dvdweb/demo/help/udf.htm
Locate the file "SCSI1HLP.VXD" in the C:\Windows\System\Iosubsys\ directory and do one of the following: Replace it with an older Windows-95 version, or
rename it to "SCSI1HLP.OLD" or delete it.
I renamed it rebooted. And now the DVD drive is found and DVDs play.

(Text of full page is below.)

(I did not try the other solutions.)

But: the comp still does not recognize audio cds.

CD-roms are fine.

Help?

Disabling UDF on Windows 95/98
Users of Windows 95 or 98 may encounter system instability or crashes when
using the DVD-ROMs. If the system crashes you are likely to see the
following error message:

A fatal exception 0E has occurred at 028:C0041DFE in VXD UDF(01)+00000E1E.
The current application will be terminated.


Resolution
This problem seems to be caused by a mysterious interaction among the
DVD-ROM and Windows 95/98 operating systems. Although Microsoft is aware of
similar problems, they have no specific fix for it.

However, we have discovered a number of workarounds for this problem. Choose
a solution that works for you.

1: Disable the UDF file system.
The DVD-ROM content is written using the UDF file system as well as the ISO 9660 file system. The problem seems to arise when the browser tries to read the UDF file system on the DVD-ROM. If the Windows 95/98 UDF file system is disabled, then the browser will be forced to access the content using ISO 9660 file system and this apprently solves the problem. Disabling the UDF file system however may cause your system not to read other DVD-ROMs that use only the UDF file system.

Instructions for disabling the UDF file system from your Windows 95/98 operating system


Click Start, and then click Run.
In the Open box, type msconfig, and then click OK.
Click Advanced.
Check the "Disable UDF File System" box and reboot your system.

2: Use a different browser. While the problem has been observed under both Netscape Navigator and Internet Explorer, on particular systems it is often the case that one or the other browser can be used without complication.

3: The following solution (found at the Pioneer Technical Support website) may work for some Windows 98 systems.
Locate the file "SCSI1HLP.VXD" in the C:\Windows\System\Iosubsys\ directory
and do one of the following: Replace it with an older Windows-95 version, or rename it to "SCSI1HLP.OLD" or delete it. On most peoples systems this file is not needed. There is no information as to why this file causes a problem, all we know is that doing the above does work to fix the above problem in many cases. The Microsoft Knowledge Base article Q281252 propose the same
workaround for Windows Me. For more information about the article, please go to http://support.microsoft.com/support/kb/articles/q281/2/52.ASP

Have you tried swapping CDROM with another mobo slot ?
regards

 

Thank you for your resonse.

The DVD is connected to the 2nd IDE port.

It now plays DVDs, but does not play audio CDs.
I think this is a windows problem. Since I was able to fix the DVDs not being recognized by changing a windows setting.

Very annoying.

When you installed the DVD, did you notice the position of the jumper on the back? It can be set by default to the CS, or Cable Select, try setting it as Slave or Master, according to the IDE ribbon connection position. The end is Master, the middle Slave.

 

Thank you for the response.

I opened the comp last night. The jumper is set to master.

One of the Audio discs I tried provided an error: "MMSystem262 there is a problem with your media device. "

Searching for this error did not result in any clues.

Wierd.

In my system.ini file, there are 3 entries containing "mmsystem ":

under [boot]:
drivers=mmsystem.dll power.drv

under [drivers]:
wave=mmsystem.dll
midi=mmsystem.dll

Make sure they're in C:\WINDOWS\SYSTEM.INI.

This one has got me stumped right now. You haven't mentioned if you have 2 CD drives. So on a reach I suggest to go into Control Panel\Multimedia. Click on the tab for CD Music and check the drive letter to be used for audio CD. You will also see a checkbox concerning digital audio and a notice there saying it may not work for all.
Another place to look is in the Device Manager, expand the CD-ROM branch, and go to Properties on the CD drive, click on Settings, check to see if DMA [Direct Memory Access] is enabled, should be. I do think it is already since DVD's work fine.
