I can't see them.
Not sure why but It won't let me play them through the Forum either (shows something about 'embedding not allowed'. If you click on the YouTube logo on the bottom right of the videoclip screen, it should bring you into it on YouTube - that works for me (I tested as soon as I added the link to the Forum to ensure it worked ok).
Hope it works for you - if not I could send them to you via email/pm ? (though I think the PM link would be the same).
By the way, I loved your recent uploads - some cool shots!
