Digimon was a real good show back in my time, when I was young. I highly doubt you can find it in higher resolution, but trying never hurt.

@salsa20 is right about datahoarders. In fact, they are currently backuping all YouTube videos about cyber security because youtube is taking them down. I will join them as soon as I get a couple of 10TB drives.

They "might" be able to help you, but it's a long shot, indeed.
