Hi Martin. You are definitely welcome to come back to this video at a later date. You have two options on how to do this. When you are on the video page, there is an option below the video that says "Later". When this screen pops up, you may choose to schedule this video for a particular date by using the calendar. Or may simply say "No thanks. Just save for later".
If you choose to schedule on a date, you will receive an email reminder 10 minutes before you have it scheduled.
If you choose to just save for a later time, you may find it by going into "My Profile" and then selecting the tab "Watch Later".
