Monday Mutant 58: Blackbarrier Jam / Streaming Content (cipher)

In the Blackbarrier Jam puzzle on the left and in the Streaming Content puzzle on the right, the given numbers have been replaced by letters; all instances of a particular letter represent the same number, but two different letters must represent different numbers. (This applies whether the letters are in the same grid or not.) The rules are otherwise unchanged.

My most sincere apologies for today's Monday Mutant being late; I was debating whether to put the series on hold for the holidays, but decided against it a few hours ago.
