I’ve tried downloading videos from several websites, not just the ones listed under the Online tab, and it’s worked fine so far. The only problem I have is the terrible download speed. I don’t have a particularly great connection, but Steam and GoG easily reach 8Mb/s when I download games, same with Mega and Drive when I download files, while this program is currently downloading a 255Mb video at 180Kb/s as I write this comment.
