These used to be on the LEGO website. I thought they'd been lost forever, but today I found a recording of them I'd made in 2010... It's not perfect quality, but it's better than nothing.
The original video file I recorded was 480x268, approximately the resolution of the player on the LEGO website. It was also 200 FPS (?!?!). When I tried uploading it directly, YouTube made it even lower resolution than it already was... So I opted to upscale it to be sure nothing would be lost. I also saved the upscaled version at 60 FPS just to be sure no "real" frames would be skipped. Maybe some day the original video files will be found again...
