Hi im searching for a on going playback problum, my old computer use to have a similer problum btw, and that was if i was playing back a video movie say a divx it would put a diagonal line across my lcd monitor now and again when ever the motion was going fast across the screen and i always thought it was my old grapnics card playing up or not up to the job, i now have a nvidia 9600GT card with quad core CPU so i would have thought this would have sorted this out, but now I get a horizontal line, this also happens when i play a video game as well btw, I do have k-lite-codec pack installed and iv tried all sorts of players with out any joy. I also get this if i play back using my 40" lcd tv so its not the monitor which is a samsung 225BW btw.
Has anyone had this problum and been able to solve it ?

Can you describe the line a bit better? Is it a single horizontal line or many of them? Are they horizontal lines extending from the edges of vertical moving objects? The latter is usually interlace lines, but you shouldn't get that with non-interlaced Divx video.
Take a look at this post and see if the photos are similar to your problem: https://forum.videohelp.com/topic357215.html#1892136 -
no its nothing like that picture, its a single line that appears in the middle of the screen and lasts a few frames and it moves up abit before disappearing, I have tried to capture this to show you but so far im not fast enough if i do manage it i will post a shot of it

I suspect what you are describing is "tearing":
https://forum.videohelp.com/topic339517.html#1769168
The line may move up and down the screen and there may be some noise at the tear.
The solution is to use Video Overlay, enable double or triple buffering by the media player, enable "vertical sync" in the graphics card's setup applet, and/or update your drivers. -
had a look at that and no i wouldnt say it looks like the picture shown its just a line

With tearing it may be hard to see the offset above and below the line. Look for a medium speed panning shot. It will be most obvious there.
If the problem is tearing you probably won't be able to post a screen cap. The cap won't have the problem because this is a realtime issue in the output of the graphics card. -
I only ever see this with a fast panning shots, cant say iv notice it with any normal speeds

When there's little motion it doesn't matter if what you see is half of one frame and half of the next. The two frames are pretty much the same. It's only when there's significant motion that tearing becomes obvious.

i thought it might have been bad encoding causing this as it only happens with downloaded review movies etc, but it also happens with in game start up video or intros as well,

iv gone into it and Settings -> Preferences -> Video. Overlay Video output is enabled.
my VLC version is 0.9.4
but I cant find these bits below ?
Settings -> Preferences -> Video -> Output Modules -> Video Output Mode (enable Advanced Options at the bottom right of the dialog). Try different options. Especially Default, and DirectX.
Settings -> Preferences -> Video -> Output Modules -> DirectX. Make sure Use Hardware YUV->RGB conversions is enabled. Try changing the Tripple Buffering setting. The other settings too.if the world of dvd was easy i would be a happy man -
just noticed that tear video sample by the way and that is it, just as im seeing it
if the world of dvd was easy i would be a happy man -
In VLC's Preferences dialog, in the "Show settings" section at the lower left, enable All. Then go to Video -> Output Modules -> DirectX. Make sure "Use hardware YUV->RGB conversions" is enabled. Enable "Use triple buffering for overlays."
I think VLC doesn't support the more advanced output methods. You should try a player like MPCHC. That is currently my favorite player. -
havn't got the option Output Modules -> DirectX. Make sure "Use hardware YUV->RGB conversions" is enabled. Enable "Use triple buffering for overlays." on my version will give MPCHC a try when i get a chance tomorrow and get back to you, thanks for your help so far btw

I have a line across the bottom of my encodes, h264 caps from hauppauge 1212 hd pvr are nice and clean, encode to xvid or x264 i get a line across bottom. any suggestions?
-
I suspect your h.264 decoder is decompressing the 1920x1080 frame to 1088 lines and filling the bottom 8 with junk (often a green or gray band but it varies from decoder to decoder). Either crop away the bottom 8 lines or find a decoder that doesn't add the extra 8 lines.
Here's a thread dealing with this problem:

awesome thanx for the link too, I was searching but kept ending up in different problems. I've used this site for reference for years, this the first I've actually had to post my own questions.

Hello Again Jagabo today Iv download the lastest version and still couldnt find the sections you told me to alter I then relised it was because i wasnt double clicking video, I just clicked it once and it only brought up one page, any way iv checked and
1: Settings -> Preferences -> Video. Overlay Video output is enabled
2:Settings -> Preferences -> Video -> Output Modules -> DirectX. and Hardware YUV->RGB conversions is enabled
So Iv tried also selecting "use video buffers in system memory" and this seems to have help at least in the one movie iv looked at so far will play some more if i find its playing up again. big thank you for this m8
BTW You say try changing this and that am i right in thinking that you didnt need to alter this and that ? because as far as i have read very few people seem to have this problum and i was wondering if it was a hard ware set up that is causing this in the first place ?
One other thing this may have help with playing back movies, but its not going to fix the in game stuff is it ? anyfix for that ?if the world of dvd was easy i would be a happy man -
I think a lot of people have the tearing problem and just don't notice or think it's normal.
You are right, changing the VLC settings won't help with games. For games try starting the NVIDIA Control Panel. In the left pane select 3D Setting -> Manage 3D Settings. In the right pane select the Global Settings tab. Scroll down to the bottom to Vertical Sync. Set it to Force On. If it's at "Use The 3d Application Setting" you have to turn it on in each individual game. You might also try enabling Triple Buffering. I suppose this might help with VLC too.
Are you using more than one display? I have two displays in clone mode (NVIDIA 8600 GT) and the refresh can only sync to one. So one display gets tearing. If your graphics card has two outputs try using the other one. -
There are two main video subsystems in Windows: DirectShow and VFW. Any particular program can chose to use either one of those or perform all its own video handling. CoreAVC is a DirectShow decoder only. Modern media players use DirectShow. Your editing software may be using a VFW based encoder or its own internal decoder instead.
