The VideoLAN Forums

I'm streaming video from my dreambox, which delivers a .TS stream (mpeg2?), and the picture quality is horrible in Vista compared to Windows XP.

Does anyone know what the reason might be?

It's also a problem on stored .ts video files - and those files play perfect in Windows media player classic...

maybe your graphic drivers or directx

Yes, i thought so too, but why does the file play perfect in Media Player Classic?

Maybe Videolan's own codecs have problems with the beta drivers - but is it possible to make it use the same codecs as Media Player Classic?

See the difference:

You cant use external codecs with VLC. You can try fiddling with post prosessing settings, Video -> Post processing

Could you try with a 0.9.0 nightly build from http://nightlies.videolan.org ?

I've tried a few nightlies already (including today's), but problem is the same.

But i made one interesting discovery: If i drag VLC over to my secondary monitor the picture looks better! (when dragging between screens it goes black first).

But other players play the video fine on all monitors.

Does disabling Overlay video output help?

Unfortunately it did not help...

Also, in Vista the Aero UI fails when Videolan plays video in DirectX mode- is that something you will fix?

There is a new Direct3D mode on nighly builds which should work with Aero.

those nightlies can be some what unstable.

When i play the files in Direct3D the video is black and white
I remember now that this was an issue in a nightly afew weeks ago also, so maybe this bug should be reported somewhere?

But at least it doesn't conflict with Aero anymore.

Does Media Player Classic video show okay on all video output methods (VRM, Overlay etc)?

When i set output in MPC to "Overlay Mixer" the same problem with Aero occurs (windows switches it off, because it says the application is incompatible). Picture is also black in this mode.

When i set MPC to "VMR9" (default), it works fine though.

i have this problem also. Its only started happening since i started using rc2 build of vista. I used to use the latest nightlie build so i could leave aero turned on without the flickering. but now the only way i get a good picture is using the standard release and turn aero off to stop that annoying flickering.

I don't know what the big deal is about Vista other than the fact that it's the newest Microsoft OS. I'm not surprised VLC is giving you problems on that platform, because it's unstable. Go back to Windows XP for the best results.

So you registered to talk about an OS you don't know anything about? Sooner or later every windows-user will use Vista, and for that obvious reason VLC should try to make it compatible also. Or even better, take advantage of the new outstanding programming framework.

Are you using MPC own MPEG-2 decoder?

so MPEG-2 video is ticked?

Yes, MPEG2 is checked.

No offense meant by my previous post. I merely meant that Vista isn't fully "ready" for VLC yet. There are still bugs to be worked out, things to be finalized/add/removed, and so on. If you get VLC to work properly on it now, something might change later which will make you have to go right back to the drawing board (for better results, anyway).

My intent wasn't to bash Vista, just to point out it's not done.

Actually Vista is done now, so there won't be any more changes there - but there may be changes in videodrivers, but they're so close to RTM now that i doubt there will be any major changes.

I just wanted to let you know that when i set output mode to OpenGL - the video plays fine, with normal quality!

I think OpenGL support was added to the nvidia beta drivers released a week ago.

However, the quality i still poor when using DirectX as output mode.
