I've got a HD demo clip to test on my pc.
The screen 've got is the Dell 2450.

When I don't play the clip in fullscreen mode the clip is ok but as soon as I make it full screen there are think lines appearing in places on the screen. usualy at the edges of objects onn the screen or round the edge.
there just like think horisontal lines.

I've had a look at my mem and processor and when the clip is being played the cpy is going to to about 75% and the mem goes to around 400meg.

My processsor is a P4 2.6GHz
with 1 gig of mem.

I've tried using media player and vlc and the same lines are appearing on both.

Any ideas what could be wrong and how to fix it ? cheers
 
Playing interlaced material on a progressive display usually looks awful. What you are describing is almost certainly the interlacing.

righty so theres no settings or anything I can change that'll maby help?

It seems to work fine maximised with just the gui border shoing in vlc it just starts happening when you remove the gui in full screen.

But I think 720 clips work fine so it could be a problem with the graphics

Click to expand...

In vlc enable blend de-interlacing.
 
just tried both sugestions and still no luck :(
just tried it on the laptop in full screen and it works ok, but then again thats not trying to output at a res of 1900x1200
 
The res will make no difference, it's the fact that it's interlaced is the problem, blend always works for me, try some of the other de-interlacing options or try opening it in Media Player Classic
 
Use discard interlacing, that always works, though you end up with 25 frames instead of 50 fields making it not as smooth. Also you can try bob deinterlacing which looks much smoother as you get 50 frames.

It looks better on your laptop because the picture isnt as big, as you enlarge the image the artifacts get worse. Where did you get interlaced video from? A digital camera? I've not seen any trailers that use interlacing instead of superior progressive.

Ah yes tv shows, we'll never be able to see the true quality of hd until blu-ray I suppose when we get 50 progressive frames instead of the half res interlaced crap, is it any wonder some people say hd doesnt look that good when they are still using 1920x540 fields and 25fps.
 
Still no luck guys tried flicking though most of the interlace options on vlc and none seem to fix the problem.

It's probably the graphics card or a combo of that and my crap PC. But the strange thing is I can expand vlc so that the size of the vlc player is bigger than the screen sice in full screen made yet theres none of the line problems :(

Might be a long shot but is there any other players that might play it better, i've tried vlc, media player, media player clasic.
 
First you need to associate it with all the file types so that it automatically starts up when you play a video in windows media player, you can do that in the ffdshow config utility. You then just need to open it up from the icon in the taskbar when your playing a video and select deinterlacing methods.
