Hello Mrs. Cherrywinkle aired from the 1990s in to the 2000s. Multiple videos exist on YouTube, however they don’t cover the full series considering how long it was broadcast. There are VHS releases as shown below. It’s unknown if DVD, Blu-Ray or streaming releases exist.
The first video is basically presumably a full episode, however only a VHS capture
The second video is a advertisement that features a small segment of said show
The third clip is the custom logo card that was used at the end of the first video
