Change default save path to ~/Videos
Summary:
BUG: 385367
Changed default save path to ~/Videos, which seems like a more humane starting location than /var/tmp.
Test Plan: Can't test; don't have any machines with optical drives. Would appreciate some rudimentary testing from anyone with appropriate hardware.
