Ah, I don't do the X-Win thing (WHICH IS NOT LINUX!@#). Linux is an OS thatis shell-based like DOS was. X-Win is a pretty GUI put over Linux that issues commands for a user based on pointing and clicking on stuff so that even people who have trouble finding the power switch can say they use Linux, when in reality they're just pointing and clicking with no clue what's really going on. Yeah I go overboard when it comes to X-Win kiddies because I used to code on the Linux kernel, and have been doing Linux forever, and it ticks me off that some people have the audacity to say they can use Linux when, if they were ata shell-prompt, would be crying for their mothers.
Anyways, were you referring to the KDE thing, or QuickTime. If it's the KDE thing, I can't really offer much help there. If it's QuickTime I can offer advice.
