"No video found" error handling

Regardless of how many sites are individually supported, or what algorithm you use to locate a video on a page it seems that there will always be instances where a bookmarklet or browser extension will not find the embedded video. In this case as a user I would prefer a less ideal experience of say, for instance saving the whole webpage, than not being able to save the video at all.

Just my two cents, love the service, looking forward to seeing it mature!
