Video url extraction failed for some videos, e.g. http://teamcoco.com/video/old-time-baseball The url extracted was also occasionally suboptimal quality, e.g. http://teamcoco.com/video/louis-ck-interview-george-w-bush
No clear method for determining if hd is available so opted to just check for presence of hd toggle function.
Valid url regex for traileraddict.com is too strict. Need to allow, e.g. theatrical-trailer, teaser-trailer, feature-read-band-trailer, etc.
