5 hours watching a video is not that unreasonable for a machine of that age, especially since it’s Intel.

According to this review they got 10 hours with wifi off, playing a 720p video that was stored locally on the machine. Youtube is going to have plenty of background tasks going on, wifi is going to be active downloading things, and you’ve probably got more than just youtube in the background so I would consider 5 hours to be expected without really delving deep into power saving (and probably killing performance).
