Seems like this one may not be available in HD… I’ve gone ahead and upscaled the DVDs to 1080p, making it look as good as I can get it. (There appears to be noticeable edge enhancement on the DVDs, which is annoying, but I did my best to work around it.) I’ve also restored the original music to the episodes that were altered.
Still, if anyone sees this later on and had an actual HD version of this series, please let me know.
