fate of the video/sound cards sections
by Diego Biurrun 20 Nov '06

20 Nov '06

I've just looked at the video card and sound card section in our XML/HTML docs again: http://www.mplayerhq.hu/DOCS/HTML/en/video-cards.html http://www.mplayerhq.hu/DOCS/HTML/en/sound-cards.html They are both horribly outdated and I'm not sure if they are useful at all nowadays that the available cards/chips have changed so much. I'm tempted to just remove the sections since nobody is going to update them anyway. Are they worth keeping? Diego
