Err, right, but I'm trying to help the OP nail down -whose- digital
artifacts---whether the 150 is having issues encoding from its RF
input, or whether it's having trouble encoding from its analog input
if fed from an STB, or whether the STB is itself having issues, or
whether everything in that chain is faithfully reproducing a crappy
feed from the headend.  From his description, I don't even know if
there's an STB in the mix.

[Perhaps you misunderstood my STB comment and thought I was saying
that the STB is just remodulating an analog signal to an analog
signal?  That's not at all what I was talking about---I was talking
about the case of taking an analog output from an STB that's decoding
a digital feed.]

Btw, I haven't actually seen the image at all---that site doesn't play
nicely with my browser -at all-, although it's quite happy to try to
spam me with popup/under advertising crapola while failing to actually
show me what the OP wanted to show.
