video quality below average
I am a translator!
When playing DVDs the video quality is rather bad. Too much noise, artifacts in black areas. I know that the DVD won't look as well as it could on my monitor, since the physical resolution of the display is way above the DVD signal. But I believe to recall, how DVDs looked somewhat better in Windows. What does the video quality depend on anyway?

Is the quality bad on all the players (e.g. VLC, GNOME-MPlayer, Xine)?

Could be your graphics card drivers.

The quality is bad on vlc and kmplayer. I've tried it in KDE so far, not in Gnome. My graphics card is the Intel X4500, so I assume the drivers aren't the problem. Will try it out in Gnome later today.

Does compiz work?
Try changing the video output, though I'm not sure what it should be, Xv
or something else.
Are you using a desktop or a laptop? Not sure if that graphics card is a
mobile version or not.

Compiz works and I use a desktop. Switching the video output in gnome-mplayer or vlc has little to no effect at all. I switched postprocessing off, which might have been a slight improvement, but the video is still quite noisy. A DVD should be better than that, it's not a VHS.
Could you post a screenshot so we can see the quality you are talking about. I haven't had a problem with my DVD quality.

Here's a screenshot from AI.
I think I'm very picky about video quality, and I don't find anything
unordinary about this screenshot. It looks like an average DVD-video
quality to me.
There's noise from the film itself, which is mainly visible in the parts
which are out of focus. There's typical compression noise, mainly
visible in areas with sharp contrast. Also some typical loss of details
in low contrast areas, again because of the compression.

hmm, ok, maybe it's just me. It really looks quite a bit better on TV than on PC screen.
I haven't tried watching a DVD directly but an iso from one of my DVDs on VLC and the sound isn't synchronised to the picture (not much). This is with Dagda.
With Slaine, the quality was bad on some videos (didn't try much, looked so bad, watched videos on Ubuntu): streaks of irregular picture (don't know how to describe it) towards the bottom of the screen.
No need to try any other video player than VLC which is one of the best. If a video is alright on Ubuntu and VLC, and not quite alright on Trisquel, it can't be VLC.
My Nvidia card has nouveau both on Ubuntu Maverick and on Trisquel (dual boot).
Videos are okay on Totem, but as I said earlier the sound isn't synchronized on VLC.

In the preferences/configuration there is an option to speed up / slow
down audio.
Thank you quiliro I'll try that but still why do we have to do that while we don't in Maverick?
