Aruba S3500 IGMP Snooping Issues.

I realize this post may violate Rule #1 as it has to do with a network I use in my "home" but regardless I am posting as I hope this may eventually help someone else in a similar situation as I have been unable to find *any* information on this topic as it has to do with Aruba switches that are EOL/EOS.

I have a pair of switches, Aruba S2500 and S3500 connected via a LACP Port channel. Plugged into the S2500 is a TiVO DVR and into the S3500, is a pair of "TiVO MINI" boxes that rely on multicast to work properly it seems.

Anyway, to cut to the chase: The Aruba S2500 and S3500 seem to come with IGMP Snooping enabled by default on VLAN1. I've spent *hours* reading through crappy HP documentation for newer models of Aruba switch that does not match the commands for the S3500 nor the S2500 since these are "end of support" devices HPE no longer even has configuration PDFs available from what I can tell.

The issue is: If I disable IGMP Snooping v3 and then turn it back on, the TiVO Mini boxes connect, and they can pick up the stream from the main DVR on the 2500. However, after a short while, they stop streaming and it seems the only solution is to remove the IGMP VLAN Policy from VLAN 1 and then re-add it, and Bam, it starts working again for a short while.

Is there a way to completely disable IGMP Snooping? should I be configuring it differently? I'm sure I'm overlooking something simple, but it seems setting the policy to "no snooping" and "no snooping v3" turns it off, but again, the "Mini" boxes cannot connect until I turn it on and wait for the IGMP table to show data again.

Does anyone have documentation and/or a configuration guide on IGMP for the Aruba 2500/3500 series? or any info on how to work around this?

Thanks.
