The German pronunciation would be pretty close to "zooza", so the pronunciation in that video isn't German, and a German accent would hinder you from pronouncing it that way (in German you can't have the /s/ sound at the beginning of a word followed by a vowel). Either way, "sooza" and "zooza" are not exactly hard for English speakers: they're just completely non-inferrable from the "SUSE" spelling.
Yeah, most of my German colleagues say "zooza" -- but saying it this way makes it difficult for English speakers to infer what you're talking about. So I say it as "sooza" even if it's _slightly_ incorrect.
