Keith,
I've confirmed in Wireshark that I am indeed seeing all the E1.31 packets being cast. Attached are a couple screenshots, one from WS to show the network traffic, and another from MADRIX to confirm that I have that adapter set as my broadcasting address, plus confirming the DMX traffic via the DMX Watcher. In the MARIX screenshot, I don't have the adapter dropdown list expanded, but I did disable all other network devices other than my enet adapter, to avoid any potential issues or conflicts there. Unfortunately, I still have not been able to successfully record any data through xCapture.
If there is anything else I can provide that would be of use to you when you have time to investigate, please let me know. Full Wireshark capture logs, maybe, or anything else. Thanks, Keith!!
