VideoSyncer од Softwulf

With VideoSyncer, whenever you are watching an online video in a series you added to VideoSyncer, it will automatically track the video time to the second. VideoSyncer also recognizes when you switch to a new episode and remembers the new url as the current episode.

You can, at any time and on any device, jump right back to the episode you left off. The episode will continue right where you left off. For example you're on your way home and are watching on the phone. You arrive at home and continue on your PC with the large screen, without having to search for the episode or fast-forwarding back to the right time.
