A big shout out to Crestron_Programmer_84 for all his help!? The problem was resolved by turning off Spanning Tree Protocol the VLAN that is used for the NVX and other things being controlled.? ?Once I did that everything started to magically work.? ?Looks like I need to do some reading to understand the relationship between IGMP and STP.
Thank you to everyone for your suggestions.
