http://ogo.nerim.net/reclockfilter/
Info provided by Harald Becker forum member.
Description:
The purpose of ReClock is to definitely get rid of jerky playback of AVI and MPEG material on a PC (or a PC connected to a TV). It's a DirectShow filter which is loaded in place of the default directsound audio renderer.
It provides a new reference clock that is locked to the video card hardware clock, in order to ensure that frames are played at the exact speed of what is expected by the video card vertical sync.
It also provides a frame rate adaptator for media files that do not match a multiple of the video card refresh rate (ex: playback of 23,976fps IVTC NTSC on a PAL TV).
Finally it is an audio renderer with hardware or software rate adaptation in real-time, multi-channel audio, and dynamic range compression capabilities.
For a full description of ReClock, please read carefully the README file in the distribution. There is also a little FAQ at the bottom of the page that answers common questions.
9.Turn off indexing for the drive.
To verify if a CD, DVD, CDRW drive has been indexed, perform the following;
Right Click on My Computer and choose Manage
Click the plus sign next to Applications and Services
Click the plus sign next to Indexing Service
Click the plus next to System
Select Directories
A list of directories that have been indexed will appear in the window to the right. Look for any entries that include the Drive letter of the optical device, such as D:\
If an entry for an optical device exists, perform the following action;
1. Double click on the appropriate entry
2. Select the Radio Button for No under the Include in the Index? Section
It is suggested that a reboot is performed at this time.
--Drive is not recognized in the system bios or by Windows at all.
Or- the drive does not play any media or has problems reading media.
1.Remove and reseat the drive.
A loose connection can cause the drive not to work properly.
If possible, remove the drive from the system and reseat it making sure it is firmly and well seated.
2.Remove the drive from device manager.
Removing the drive controllers from device manager and rebooting to let Windows reload them sometimes helps.
Win95,98,ME:
Right click on My Computer, click on properties.
Click the Device Manager tab.
Click the + next to CDROM
Click the appropriate device entry that appears under CDROM then click the REMOVE button.
Perform this step for any other devices listed under the CDROM category.
Reboot the computer.
Win2000, WinXP:
Right click on My Computer, click on properties.
Click on the Hardware Tab.
Click the Device Manager button.
Click the + next to DVD/CDROM devices.
Right click the appropriate device entry that appears under DVD/CDROM then click Uninstall.
Perform this step for any other devices listed under the CDROM category.
Reboot the computer.
3.For Windows95,98,ME Check for the NOIDE Error.
Click on Start, Run and type in: Regedit.
Then click OK.
You will get a Registry Editor window.
Click on Edit, Find.
Type in: NOIDE
Click Find Next.
If the search finds any icons with NOIDE, delete those icons.
Then close all windows, and reboot the system.
4.If the drive is in MS_DOS Mode or does not show up under My Computer, and may also have a yellow exclamation in device manager.
Install an Antivirus program and run a full virus scan.
A virus will cause the cdrom drives not to work properly to keep you from cleaning out the virus.
If you already have an antivirus program installed, run a full system scan.
If you don't have an antivirus program installed, try to install one and run a full system scan.
If you are unable to install an antivirus program because of a possible virus, get a dos version of the program to run.
5.Reset the bios defaults if applicable on the system.
Resetting the bios defaults resets any bios settings that may have gotten corrupt.
This should allow the cdrom drive to redetect if the problem is caused by the bios.
You can find information on how to do so on the following sites:
--How do I restore the Setup Defaults on my Dell™ Inspiron™ portable computer?
http://support.dell.com/us/en/kb/document.asp?DN=1035265
--How do I restore the Setup Defaults on my Dell™ Inspiron™ portable computer?

--How do I restore setup defaults on my Dell™ Latitude™ system?
http://support.dell.com/us/en/kb/document.asp?DN=FA1035267
6.Update your bios file to the latest version.
Go to the main Dell Support site:
https://support.dell.com/register.aspx
Input your service tag number and click "Sign in to Standard Support".
Click the Downloads button.
Under the "Select Your Download Category" section, choose "Flash Bios Updates".
Then click GO.
Click the Dell XXXX XXXX System Bios link that comes up.
Click the Dell XXXX XXXX System Bios link that comes up again.
Click on the file name XXXXXX.EXE for FLOPPY version.
Click Download Now Using HTTP.
Save the file to your desktop.
Put a blank formatted floppy in the floppy drive.
Double click the file to create the bios update boot floppy.
Once that is done, leave the floppy in the drive and reboot the system.
The bios will be updated when the system boots to the floppy.
7.Try upgrading the drives firmware revision.
Find the model type of the drive.
Then go to the Dell downloads page and put in the model type of the drive to see if there are any firmware updates for it.
Go to the main Dell Support site:
https://support.dell.com/register.aspx
Input your service tag number and click "Sign in to Standard Support".
Click the Downloads button.
Put the drive model in the search box and click GO.
If there is a firmware updated listed, download it, create the update disk, and update the drives firmware.

Question:
How do I find out what model of Hard Drive, CDROM, CDRW, DVDROM drive I have?
Answer:
Win2000 WinXP:
Right click on My Computer, click on properties.
Click the Hardware tab.
Click the Device Manager button.
Click the + next to DVD/CD-ROM drives.
You should see your drive listed, an example would be: Lite-On LTN483S 48X MAX.
The drive model number would be "LTN483S"
--Another way to tell is to check the system registry.
You can use the steps below that are listed for checking the drives firmware revision.
An example of a drive listing in the registry would be:
IDE\CdRomLite-On_LTN483S_48x_Max_________________PD03____\5&261012d&0&0.1.0
The drive model number would be ""LTN483S""
Question:
How do I find my DVD drives firmware revision in Windows XP:
Right click my computer,manage,expand storage,removable storage,libraries
right click on your drive,properties,device infomation.
-------------------------------------------------------
8.Uninstall any 3rd party programs.
If you installed any 3rd party programs before the problem started, (Roxio Easy CD Creator, Nero Burning Rom, Intel Application Accelerator), then uninstall the program and reboot the system.
Also reinstall your DVD decoding application such as PowerDVD, or WinDVD.
If the application is corrupt, reinstalling it will solve the problem.
9.Test the drive in dos.
If your floppy drive is external, attach it to the system.
Have your cdrom drive in the media bay in the system.
Put in your Windows CD in the cdrom drive.
Boot to a Win98 or WinME dos boot disk using the floppy drive.
You can download a dos boot disk from http://www.bootdisk.com
I like using the "Windows ME non-OEM" boot disk.
Once you have booted to the dos boot disk, A:\> try accessing the cdrom in dos.
If you can access the Windows CD, the drive is working and you probably have a Windows problem.
If you cannot access the cd in dos, then the drive is probably bad.
10.Test the drive using the Dell Diagnostics.
You can find information on how to run the Dell Diagnostics on the following site:
http://support.dell.com/us/en/kb/document.asp?DN=1060550#toc
11.Test another drive if possible.
-Try another drive in your system, does it work?
If so, your old drive is probably bad.
If not, the cdrom connectors on the motherboard are probably bad.
-Try your drive on another system, does it work?
If so, the cdrom connectors on the motherboard for your system are probably bad.
If not, then the drive is probably bad.
12.If all else fails, contact tech support to get a replacement drive.
If you are out of warranty, you can purchase another drive from Dell Spare Parts.
