I've spotted a few:
1 On Bentley The Robot and Other Stories, Toybox 4 and Fireman Sam's Bumper Video, Cridlington's name is spelt as Bridlington for the Brass Band description.
2 On The Biggest Fireman Sam Video Ever, it says that What Goes Up was previously released on The New Adventures Of Fireman Sam, but it wasn't - it was on Disaster For Dinner and other Stories.
3 On Toybox 2, Lost In The Fog reads out Lost In A Fog on both the box and when the episode is shown. The title was corrected on Toybox 2 on 1, but it still read Lost In A Fog when the episode was shown.
4 Spot Of Bother which is on The Biggest Fireman Sam Video Ever doesn't mention that it was previously released on The Greatest BBC Children's Video Ever! The episode and Noddy and the Special Key are both on Toybox Bumper Video and both mention that the episodes were previously released on The Greatest BBC Children's video Ever! but unfortunately the exclamation mark is missing when Spot Of Bother mentions this.
