use new videos

New videos are being created at:

We probably need to split these out into per-month subdirectories and then reference them in the DataViewer. That is a task for Jon. Jon also needs to create a script to populate an archive with videos for previous days. Overall tasks include:

• 1) Jon rewrites script to place videos in per-month subdirectories
• 2) Hans updates DataViewer to point to these new videos
• 3) Jon writes script to populate the archive
