Video Playback Issue


Question

I have a odd one that I have never seen before, and short of reinstalling windows don't know what else to try.

A couple days ago my laptop stopped playing video files of all formats.

Windows media player will give the following error message:

Windows Media Player cannot play the file. The Player might not support the file type or might not support the codec that was used to compress the file.

And Media Player Classic Home Cinema encounters a problem and has to close.

All videos have previously played in these players, and are all stored locally on the computer. I have tried installing K-Lite codec pack to see if this would fix the issue but I still have the same result, and rebooting my computer has no affact.

Has anyone else ever encountered this or may no something else I can try?

Unless your movies are in some rare, obscure format, codec packs are generally a big no-no. If you MUST use a third-party codec pack, I suggest CCCP (Combined Community Codec Pack) or Shark's codecs. They're proven to be reliable and safe. You could also try VLC, but since you mentioned MPC, I assume you have your reasons for using it over everything else. Anyway, I suggest removing K-Lite and trying one of the above packs. If that doesn't work, try a restore point. If that doesn't work, Google it or do an in-place install of Windows 7.

Hope I helped!

I had no codec packs installed until I installed k-lite. Removing it didn't help.

Here is another odd symptom I am having, youtube. All videos are only audio and the video it self is just a blank green screen. So flash player isn't playing videos either, this is totally weird.

going to try to in-place install later this week if I can't figure it out.

Have you tried updating video drivers and Flash? (I assume you have, but never hurts to ask.)

Strange how everything was working fine until recently. Have you installed anything that provides its own codecs? For example,

Fallout 3 had issues with certain codecs being installed.

Oh, and I forgot to ask: Did you have MPC set to play videos in your browser instead of Windows Media Player? I don't use it so

I am not sure. VLC has its own little plug-in too (for example) so maybe that's part of the YouTube/Flash problem?

The only thing that has changed / I installed is I downloaded from adobe's website the CS5.5 Master Collection Trial and installed that 2 days ago. I own CS3 Design Premium and wanted to try out the newer version, dunno if that could screw things up.

I treid updating flash and video drivers, that didn't help.

as for MPC, dunno if that is set to play in browser instead of WMP or not. Not sure that would make a diffrence. Besides, doesn't youtube use flash anyways?

It seems quicktime / itunes is having trouble too. They are playing only audio and blank black video. this is strange indeed, I didn't know a issue could affect all programs across the board

1. Uninstall / reinstall WMP

- Open Control Panel -> Programs and Features.

- Click Turn Windows features on or off in the left pane.

- Expand Media Features, uncheck Windows Media Player. Click Yes to continue, and click OK to quit. Then Restart.

- Open Turn Windows features on or off again. Turn on the features Windows Media Player and Windows Media Center. Restart.

- Launch Windows Media Player, initialize the program.

Note: If you turn off WMP, Windows Media Center will be turned off either. You may need to re-configure settings for Windows Media Center after re-enabling it.

2. Try Fix WMP Utility

3. Try MS Fix IT here and here

4. Try Codec Tweak Tool 5.0.8

5. Update your graphics card driver

6. For MPC - try a different video renderer in Media Player Classic. Options -> playback -> output

YouTube problem:

1) Right click on YouTube video.

2) I get these tabs: Display, Privacy, Local Storage, Microphone and Camera.

3) Under Display, UNCHECK the ''Enable hardware acceleration'' tickbox.

the problem ended up being the graphics driver. It said their was no updates available, but going to amd's page and getting the latest radeon drivers seem to have fixed the issue
