[Solved] Poor DVD image quality

I haven't been able to find ANY thread or info on this, so if there a thread already, i apologize.
When using VLC to watch DVD movies, i get a VERY poor quality. Perforance is ok, and I wouldn't mind worse perforance if it meant better quality. I tried all of the video output modes, but none seem to improve (they only have same or worse quality).

Meanwhile, Media Player Classic and "The KMPlayer" with VRM9 Renderless give VERY good video quality.

I'm running windows server 2008, system specs should not be an issue (gforce 8800 - athlon x2 4800, 4gb ram)

So, any ideas on how to solve this? Some tweak i'm missing? or is this just a bug? The dvd playback quality is just TOO poor.
Oh, I can post screenshots of both if you'd like to see a comparison of what i mean.
BTW: used same dvd and pc and everything for the MPC comparison.

thanks for any help in advance :D

That's hard to say, but I got a few ideas:
You should check wether accelerated playback and conversion from YUV to RGB is enabled.
Furthermore you you verify that the filters and shapes a set to default and not distort the movie.
Or maybe VLC cannot handle you DVD drive appropriately. Maybe you should make ans ISO-Image of
your DVD and open that with VLC to exclude this as cause of defect.
Btw are you runnig you other software players where the DVD runs well also on Win Server 2008?
Sometimes the Server Operation Systems don't come along with all required codecs?!

Yup, both are enabled.

Nope, they're all off. I should mention that non-DVD video playback looks just fine.

Made an ISO, same thing

Yes, the other two i tried where on the same pc+os
I'm not sure if this OS has all the codecs or not, but does VLC use and system codecs which MPC doesn't? How can I tell if i'm missing some codecs? (since i'm not sure which are needed for dvd playback)

The usual DVD "quality" problem is teleciné, which makes the video look like it's interlaced. Enable de-interlacing ("X" works fine) from the video menu.

Problem solved :)
