Something I noticed recently is that on occasion, EUMETSAT streams would appear in the MM. I deleted them manually in the admin interface, as they are not video. Originally, the script was supposed to ignore streams with IPv6 sources (bc the relays do not support AMT for IPv6) and EUMETSAT sources (since they are not video). So may want to check if that still is part of the script.
