Hello Tony!
Yes, I know this familiar sound! They even released a CD with theme songs from Mr. Sattler as the demand was apparently very high
Unfortunately it's just the shows, not the actual waiting/background music, but the style is so "him". It might also be a fact he used the same equipment for all of these, so overlaps in sound and style is naturally happening.
There is something so familiar with these tunes, back then when TV time was so much limited - either while my parents watched about me spending time outside or because it was just not so much in the focus of our lives. Fixed programme schedules that made you buy a VCR (and program the ShowView numbers if you could..), commercials and overall often stale shows. But then, when the family would meet in front of our PANASONIC with snacks, each in his/her seats (and don't dare to sit on MY seat) and watch Glücksrad (Wheel of Fortune) or Der Preis Ist Heiß... And then that music.
There is a mid-90s SELECTED SOUND album called TV SHOW TRAX that is much more Eurodance'ish, but "Top Then" from that particular album is also something that clicks so hard with me I wonder if I subconciously remember it from somewhere.
EDIT: Oha, now the circles closes up. On Youtube, there is a Sattler/Janda track from the ARCADIA COSMOS series, and the uploader is Joakim, probably the same Joakim95 that is on the forums and shared the Oranger Power album. Köberl/Janda/Sattler are a pair just too well known. It's this combination of Austrian artists creating these familiar sounds..
