Roloccolor ...the process that is a cache download to your HD in order to view something is NOT a copyright issue.
Don't try to confuse people.
The 'share' link on their video content is within their TOS [obviously], but the EXTRACTION of their content for replay via OTHER MEANS is not.
Of course, the assumption is that THEIR content is actually THEIRS to even display.
MOST of the content is in violation of others' copyright anyway.
Uvah....yes...it's what you do with it.
