Hey peoples.

I turned of my computer last night, and went to bed and slept.
Turned it on this morning, went to watch a video, and there is sound but no picture.
At first I thought it might be a once off, so I restarted.
Same thing happened. So I tried Media Player classic, same problem there. I tried WinAmp, same thing.
I thought it might just be videos, so I tried a DvD - and the same thing happened.
I download DivX, and it is the only thing that plays videos.

So I got thinking if might be codecs. So I un-installed all my codecs, and then download and installed the K-Lite codec pack full.
It didn't do the trick.

So I went to my graphics settings, and turned off all hardware acceleration - and now everything plays fine, full picture and sound.

Then I downloaded the latest drivers, and that didn't do it. So I downloaded the latest Omega drivers, and that didn't fix it either.

I'm running Windows XPHome, P4 2.4, 2gigs RAM, ATi Radeon X800 Pro 256mb.

Please help this is really annoying.

Oh and I tried to play a game with full hardwhare acceleration turned on, to see if the GFX card was flunking, and everything worked fine(I tried a few different games) and had no problems.

So yeah, any suggestions?

Firstly bump.

Secondly, something weird.
If I open a video file in any media player, I get no picture. But if I leave it open, and open ANOTHER video file in a different media player, I do get a picture.
But as soon as I close the first media player, the picture goes black.
Any ideas pleaseeee?

Sounds like you tried practically everything. what happens when you boot up in safe mode and open a video?

G'day used the tool.
Didn't change anything.
And I can't restart into safe mode (haven't been able to for a while, that was going to be my next forum topic).

Do you have problems with all of them?

I was curious when you said:

"If I open a video file in any media player, I get no picture. But if I leave it open, and open ANOTHER video file in a different media player, I do get a picture."

it seems like the Second one "activated" something that the First one "required."

Yes it's a problem with any format, including trying to play DvD's.

Yeah you see that's what confuses me.
Cause at first I thought it was something to do with my graphics card, cause if I turned off hardware acceleration down nothing, the videos work.
So I updated my drivers, and switched drivers, adn tried different settings and codecs etc and nothing changed.

Then I stumbled upon the having 2 players running thing.
So I am really confused.
Cause according to what windows, the same codecs are running when 1 or 2 are open and playing.

You said that you "turned off" hardware acceleration, can you "adjust" it instead? In other words, is it possible to take it down a notch rather than turning it off?

http://www.pptfaq.com/FAQ00129.htm

"What happens when I turn down hardware acceleration?
Windows uses your video driver to put graphics and text and animations on the computer screen. Some video cards and drivers have more advanced capabilities than others, so Windows first asks the driver "Can you do this" and if the driver says it can, Windows turns the task over to the driver.


Most of the time this works out well. The video manufacturer's own software can usually do a better and faster job than Windows itself can. But sometimes there's a bug in the driver software and it can't really do everything it claims to be able to do. That's when you see video problems in PowerPoint or other programs.


Every time you turn hardware acceleration back a notch, you're telling Windows to handle another group of video tasks itself rather than turning them over to the video driver. Windows may handle these tasks in a simpler and slower manner but it's more standardized and reliable, so letting Windows handle it may eliminate the video problem."

I still can't help thinking that this is a codec problem.

I want you to uninstall all of your codecs and as many players as you can. Then delete the folders that they were in. For example, delete the folder "C:\program files\Divx". I don't want there to be any "configuration" files left over.

After that, download K-Lite Codec Pack Basic 3.5.3

http://fileforum.betanews.com/detail...c/1094057842/1

During installation, make sure you checkmark something like: reset all options or configurations, or something like that. I want everything back to default.
