I cannot reproduce with Vimeo videos specifically, although I can observe that quoting the example URI that you give indeed fails.
Here is what happens when I try to play e.g. the first video of the HD channel ("Phoenix - 1901 - A Take Away Show"): - unquoted URL: http://vimeo.com/moogaloop/play/clip:7942520/063aa13b9e53ae2fa551a8f7cdeca33b/1259933400/?q=hd - quoted URL: http://vimeo.com/moogaloop/play/clip:7942520/063aa13b9e53ae2fa551a8f7cdeca33b/1259933400/%3Fq%3Dhd
which is then successfully redirected to http://bitcast.vimeo.com/vimeo/v2/125/878/12587819.mp4?e=1259934410&h=c94226a1f866b49aaf12be4cf7f4a3f2
