I wonder whether there is a away to improve the movie sound. For example when I watch trailers on imdb Hugo Trailer (No. 2) - IMDb the sound is simply astonishing, is there anyway to improve the sound in the videos to that extent?
I use vlc for playing videos.
Why vlc?
It plays fine in the web flash
Same here (FireFox).
You misunderstood me 
I never had a movie with such an excellent sound quality as for example in that trailer. So my question was, is ithe problem the dvds quality or maybe vlc, because I use vlc to watch movies on my pc.
Some have found installing: vlc-auot-pulse
Can help
Check your audio settings here in vlc: http://dl.dropbox.com/u/10573557/SUSE%20Misc/vlc_audio_pause_resume_issue.png
Try different settings
I mostly use SMPlayer for movies
VLC for DVD’s
Will play around with those setting, thanks. You probably meant vlc-aout-pulse though
Sry doublepost.
Yes. My typo
