Hello Mrs. Cherrywinkle aired from the 1990s until the early 2000s in US and Canada. Three videos exist on YouTube and two others on Dailymotion 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. It was a musical show as evidenced by the name on the first VHS cover.
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
