The error console reports:
The page at 'https://my.mayday.us/t/03c7-Jeremy-P-White/' was loaded over HTTPS, but displayed insecure content from 'http://pdl.vimeocdn.com/67714/626/259408602.mp4?token2=1401885285_e084aff7f41ac4cc6ab8caac4a0639f9&aksessionid=9a1052a8cfd4dd96': this content should also be loaded over HTTPS.
Looks like the main page gets this as well.
Not sure if this is worth fiddling with at this point; just being thorough.
