Continuity mistake: When the Hulk throws the tire during his second transformation, the first shot shows a horizontal trajectory but the second shot shows a 45 degree angle trajectory, which makes the tire land much further than expected.
Time Squad - S1-E4
Continuity mistake: During Blake's first encounter with Cally, the smudges on the front of his tunic (including a big chalky footprint left by her boot) disappear, reappear and rearrange themselves several times between shots. (00:31:20)
Saga of a Star World (1) - S1-E1
Continuity mistake: When Baltar turns to face the two setting suns, we see the lower one at the left has what could be a boat in its reflection on the water. The higher one on the right is over a mountainous area on the horizon. The next shot is of Baltar in close-up, then the next returns to the horizon to show us Baltar's view, which shows just ONE setting sun. The one on the left has vanished though there is room enough for it to have been seen in this shot. (00:40:15)
