Windows Media Player 9 lists the title of the DVD that comes with the free glow-in-the-dark stickers as "Let's Start A Band [With CD]" when the DVD is inserted while the PC is connected to the Internet. Um, what CD?
The box of the DVD insists that the DVD will only work on Region 1 (USA & Canada) DVD players, but a quick scan with DVD Genie reveals that the DVD will also work with region 3(South-East Asia) and 4(Australia, New Zeland, Mexico, Central & South America) DVD players.
In the song "Betcha Can", the words "Betcha Can" are captioned as "Bet You Can"
The Dragon Tune "Doodli-Do" is captioned as "Doodly-do." This mistake is not present on the sing-along content featured on the DVD version.
In the Dragon Tune, "Hello," Ord's name is incorrectly captioned as "Org" in the line, "Hi, Hello, My name is Zak, Wheezie, Ord, Cassie." This error is not present in the English subtitle caption track.
PBS online listings incorrectly give the names of Sam and Jennifer as Sarah and Joey.
In "The Grudge Won't Budge" the dragons just slide along the ice instead of wearing iceskates. This is different from past episodes.
In "The Balancing Act," when Max and Emmy are crossing Fuzzlebush Gulch, the skateboard tracks appear on Ord's log, but they should be on Emmy's, as that's the one it slid across. (Thanks again, PBSKidVid)
When Zak and Wheezie dive to land after Cassie loses her basket, the bandage on Zak's wrist disappears for a time until Zak moves fully into view again.
In "Try it You'll Like it", Max, Emmy and the dragons all go into the park. As they enter, you can see other dragons come into the park. When they see the ride The Skipper for the first time, there are also other tourists on the ride laughing and having fun. Throughout the show, when they go to the snack bar and while they try out new rides, how come there's no tourists around? By the end of the day, they leave the amusement park without other people around.
In "So Long Solo," the group in the evening tries to find the jugglebug for Zak's performance. When the jugglebug finds the dragon corn trail, look sharp, you will see a green heel. Before the zoom-in, Wheezie was closer to the trail, and the jugglebug went by Zak & Wheezie on their left. The heel was supposed to be purple as Wheezie occupies that side.
In one of the scenes from "Hands Together," the animators forgot to assign Cassie a mouth.
When Lorca turns to say that Ord should look somewhere new, his wheelchair moves seemingly all by itself. His arms don't go outside the armrests.
In "On Thin Ice", when Zak and Wheeze see Icicle Falls, Ord, for an unknown reason, is wearing a yellow helmet.
Max and Emmy return home at the end of "The Shape of Things to Come" without saying the rhyme.
After Quetzal slices a piece of cake near the end of "On Thin Ice," the rest of the cake magically disappears from the table where he set it down before he slips and falls.
It seems odd that Emmy's real-world basketball team and the School in the Sky basketball team have identical uniforms.
Cassie can't play in the game because of her hurt foot, yet she seems to have no trouble jumping up and down on the sidelines. However, she did say that it only hurts when she runs.
The others offer a lot of advice (both useful and not) to Emmy when she's being teased, but not one of them so much as offers to stand up for her.
When Emmy is "making herself clear" for the second time, it looks like an animator borrowed a bit too heavily from Lorca's design to make the red dragon on the School By The Lake team. He looks almost exactly like Lorca, with the exceptions of the wheelchair and the longer spikes.
When the other team is teasing Emmy because she can't fly, he looks more distinct from Lorca; lighter color, different teeth, and a longer neck.
