The Wiggles is definitely on Disney. Rovingbar is CST and I'm PST so my Guide entries are two hours earlier than what he posted. You can record them all by:
EDIT - These steps match what I had to do on a 942. Your 622 might differ somewhere.
Hit the DVR button until you get to Daily Schedule, cursor to DISHPass & Select
"Text Msg in" The wiggles
Cursor to Priority & Select, then Select Move to top, Down to Done & Select
(It doesn't need to be Top priority, but makes it way simpler to find it in Timers list)
Cursor to Set Channel & Select, Select to check the Set Channel, enter 172 (DISE), down to Done & Select,
Cursor to Create Timer & Select.
You might also want to select Options and restrict it to 5 or 10 Episodes kept on the receiver. That can be done later, as could the restriction to Disney East. Even my Grandchildren have passed "The Wiggles" at this point, otherwise I'd probably record a bunch of them and burn them to DVDs myself.
That should give you two episodes of Wiggles Tue-Fri and a single episode Sat-Sun-Mon. Mine are 4AM (every day) and 8AM PST (Tue-Fri only). The actual schedule for channel 172 is
3:30 - 4:00 JoJo's Circus
4:00 - 4:25 The Wiggles
4:25 - 4:30 Go Baby
7:00 - 7:30 Charlie & Lola
7:30 - 7:55 The Koala Brothers
7:55 - 8:00 Shanna's Show
8:00 - 8:25 The Wiggles
8:25 - 8:30 Dan Zane's House Party
On a Name based DVR, when I highlight the 3:30-4:00 item and hit Info, it shows exactly that half hour block. If I move to the right to the 4:00-4:30 block, it identifies it in the Guide as 4:25 and Info button shows it 4:25-4:30 with no indication of anything being on 172 DISE from 4:00-4:25. Search is able to find that show just fine and DISHPass will record it just fine as well.
The block before the 2nd showing includes another show (The Koala Brothers) that has the same sort of problem. On my Name based 942, the 7:00-8:30 guide displays as
7:00 Charlie & Lolo
7:30 Shanna's Show (with 7:55 mentioned)
8:00 Dan Zane (with 8:25 mentioned)
On my TIME based 508, that same block displays as
7:00 Charlie & Lolo
7:30 The Koala Brothers
8:00 The Wiggles
There are similar problems with some 15 minute shows on Comedy Central. You can do a Search for "Robot Chicken" and find the shows displayed, but they aren't the LAST show to start in a 30 minute block so you can't easily create a regular Timer for them. When you attempt to create the Timer, it creates a timer for a show with a completely different name. It does show you the name of the show it is about to create the Timer for - but we are pretty accustomed to just hitting Select. After all, how could DISH possible get the Name of the program wrong when you are selecting something from a list the receiver just created.
You shouldn't assume the Guide is correct when you have trouble recording something. To start with, DISH takes all the published Start and Stop times for all shows on all channels and rounds them off to the closest multiple of 5 minutes. The Wiggles is actually 25 minutes long, but your Guide would still display the same :25 starting time for what follows it if it started at 7:23-7:27.
