I loved those book and tape sets when I was a kid. I actually ended up learning to read at a second or third grade level when I was 3 years old thanks to a combination of those and the Sesame Street show.
HBO's online schedule shows Sesame Street on HBO Family every day except Saturday at 6:30AM-7:30AM and seven days a week at 8AM-9AM Eastern time. There's an episode of Pinky Dinky Doo inbetween.
Looks like, at least during the month of January, all the HBO Family episodes are from Season 45...
There was a slight mistake in the copying of 1452 apparently. It starts out as 1458, but partway into the first street scene, changes to the start of 1452. Since the file only runs an hour, the last few minutes of the show are cut off.
