Lycander, Apple needs to impose QuickTime, no matter which player is used the most often. They'll probably force PC users to install it, even if it's easy to just put some part of QuickTime in iTunes for Windows. What they matter is that the containers and codecs they support can be played on most of the computers of the world. I don't totally disagree with what you're saying though because I also think that at the moment, the competition is better than Apple on the media players market as you can see on the end of my posting, I'm quite disappointed with Apple's free player.
Dlloyd, I think a lot of threads here link to other sites, my site is non-profit, but, ok, it's me, mentioning my own site, let's call it advertising then. So if you really think it's not revelant to the forum, not interesting and that it's just for having free advertising and making money, then you should alert the administrators so that they judge by themselves if they drop the thread.
