Bad quality movies in Ubuntu/Kubuntu
when i play movies with any media players in windows, the quality is better than Linux. i have searched the net but no solution. it looks like the edges are too sharp (in a bad way) and are noticeable. i think that it might have to do with anti aliasing, but not sure. lets say it's like playing a video game under 800*600 with no anti aliasing! of course when i make the size of the movie smaller the quality gets better.
Please help, because the only reason why i use windows is because of my movies. |
Sounds like your graphics card may not be configured optimally. Give us make and tell us whether you are using generic drivers or manufacturer drivers.
|
It is a radeon 9600xt. I haven't installed any drivers so i guess, it is the generic drivers.
|
I suggest getting the drivers from ATI and installing as per their readme to get the best performance. I use an Nvidia card and the performance with Linux is superior to W32.
|
i checked their web site, and it's difficult to install the driver, from system requirements point of view. by the way thanks for your reply.

I succeeded in installing the ati driver, but the quality is still bad, worse than windows. here is how my setup looks like:

Take a look at the x.org log file in /var/log. There are many articles on the net about tweaking the performance. Is the kernel agp module been installed?

I found the solution in another forum. all i had to do was Try different video outputs. For example: install xine-ui and set the video output to xv in the preferences. and changed this settings :
Code: Section "Device" Identifier "ATI Technologies, Inc. Radeon 9600 XT (RV350 AR)" Driver "fglrx" BusID "PCI:1:0:0" EndSection to this Code: Section "Device" Identifier "ATI Technologies, Inc. Radeon 9600 XT (RV350 AR)" Driver "fglrx" BusID "PCI:1:0:0" Option "VideoOverlay" "on" Option "OpenGLOverlay" "off" EndSection so that it wouldn't lag. i will take a look at that x.org file though, sounds interesting and useful, and what do you mean by: Is the kernel agp module been installed? |
