Ranting on the X protocol

I am not sure if your questions were aimed at me? What do you mean by X11 forwarding? (via ssh?) Via normal X11 (non ssh) the videos are just fine (not blue). I don't work remotely over slow links, I use X on my home LAN only. As for sound, I don't use any X11 or VNC features for it, I just use PA and multicast so I can hear what I want anywhere on my LAN, works fine. Again, I am not criticizing VNC, I think it is great too, but it is different than X and not a good substitute in all use cases. And, as with most software, it helps to have multiple solutions available since sometimes they don't all work perfectly.
