A page with multiple video players (youtube) each having playlists with thumbnails

Some time ago, I was asked here to create a page with multiple video players (youtube) each having playlists with thumbnails, as a replacement for the youtube app on iOS for showing youtube playlists with thumbnails, which doesn't work seem to work well (on ipad/iphone). I made something that turned out to not exactly be what the person asked for. I forgot all about it until I suddenly had an idea on how it might be done. Here is the result, with lots of explanations. (I hope this is what was asked for).

Seems to be working for me. (If you recall a similar demo page crashed Firefox for me. Maybe it was something else on that other page that wasn't working.)

Thanks Daniel, that's very helpful. I'll rebuild the other demo you're referring to along the lines of this demo. (This demo has different divs for different playlists. The 'crash-provoking' demo had one div for all the playlists). Although FF didn't crash on my computer with the other demo, I now know how to make it safer. Thanks,
Arie.

tested and working in; safari 5.1.7, google chrome 22.0.1229.79, internet explorer 9 and opera 12.02
The only issue appears to be:
in opera, the div full of video icons is not high enough, and the bottoms of the icons are being cut off.

Yes, I noticed that too. It's because of the horizontal scroll bar, I think. It's no real problem, because it's only noticeable after viewing the page with other browsers too. But if it's annoying, I could repair this with a if(window.opera) line.
Thanks,
Arie.

I think that it is noticeable enough to be worthwhile changing, simply for script compatibility if nothing else.
