You know what? The fact that the vid doesn't play normally, and magically opens fine in new window makes me think Archos is playing games with their customers. Can anyone explain why the same video doesn't play in regular window? Might be that Archos disabled this feature on purpose, but forgot about this "new window" feature of YouTube? Who knows )
As far as I know, the Archos 5/7 cannot play youtube HQ or youtube HD. Another way to say, it doesn't show "HD" or "HQ" for you to click on.
That's another interesting issue to investigate. Does this mean Archos meddle with the HTML content of web pages? Why on earth wouldn't they respect their customers?
There are no games being played, we would love you to be able to play all videos on the internet. But, for youtube and many other video sites our hands are bound at the moment. Youtube decided to switch to Flash10 for its Flash player and this Flash 10 is not available for any platform other than X86 at the moment. Adobe has promised Flash 10 for ARM since a long time and at the moment it is said to be there in Q1 2010...
Why it still plays when you do "open in new window" I cannot say, we will analyze that.
There is another way to watch youtube videos which is via http://www.youtube.com/xl
this "xl" website has been done for e.g. internet enabled TVs and therefore still uses an older and compatible Flash version.
Also we do not meddle with the content of the webpage at all, but you have to understand that at the moment the full youtube experience can only be had on x86 PC and Flash 10. As said we would love to change that...
