dvd playback issue

  liverpoolee 14:46 01 Jun 2007

hi new member here,
i've searched for hours on many forums for any relevant information to my problem but to no avail.
Just recently, putting DVD-movies in my PC has resulted in stuttering playback, regardless of the playback software. Also, the mouse and general responsiveness of the PC stutters to an absolute snails pace.the same thing applies to other files such as vobs.avi's,divx etc.
the pc will play files like youtube video's ok.
i've even tried reformatting the drive,still nothing.i've checked all IDE cables and connectors inside the machine as well.
i'm not absolutely certain but it may coincide with me putting a NVIDIA GeForce 7800 GS graphics card in it late last year.but how will that affect it?.
i'm really banging my head against a brick wall here.any help appreciated........lee

Have you tried using a cleaner disk on the DVD/CD? They have a small brush in the playing surface that cleans the laser lens as it rotates. A dirty lens caused me problems recently and cleaning it not only made DVDs play smoother/properly but the colour seemed better as well.

Try clearing out the upper and lower filters in registry.
Can help get the optical drives running properly.

Create a restore point 1st,then follow these instructions.
1. Click on Start --> Run --> and type in 'regedit' followed by the enter key
2. Expand the "HKEY_LOCAL_MACHINE" key (looks like a folder) by double clicking it (or
3. clicking the "+" next to it.)
4. Expand the "SYSTEM" Key
5. Expand the "CurrentControlSet" Key
6. Expand the "Control" Key
7. Expand the "Class" Key
8. Please look for a key containing the following string of letter and numbers:
9. High light this key by left clicking once on it
10. On the right hand side you are looking for "UpperFilters" and "LowerFilters" under the "Name" column, once you find these please delete them by right clicking on them and choosing "delete"
11. Exit the registry.
12.Reboot comp.

I`m grabbing at straws here.

Have you tried shutting down any other applications that may be using CPU time or RAM whilst trying to run the DVD. It is possible that, for example, your anti-virus is doing checks and causing the process to be interrupted.
