I viewed on a PC and the quality looks great. I don't have an Ipad o compare it to though. I wish Quicktime could do something about the load time. That video took about 30 second to load. About 65% of my visitors don't spent that much time looking at my site each visit. I still use the .swf format as there is no buffering, so there is no wait.
As always, you have a beautiful view there.
