I'm sorry to hear that. My attempt to help you there can be found at the ->
Tech Talk thread.
I was surprised to see only HD videos, too, and have my troubles downloading them, too. But that depends on the time of day I download.
Maybe Rob and Danielle are willing to add a low res option, again. (Which unfortunately would mean double the time encoding the videos.)
I'm sure quite a few members would appreciate low res videos for quick glimpses or because they can't view HD videos.
