RD,
Lets step back a little and get some more details:
* What type of DME are you using?
* What is connected to the DME providing the LIVE stream?
* Specifically, how do you have the DME configured for your setup?
* Please provide the SCREEN CAPTUREs of your DME configuration on
the SNS
* Have you configured a "Basic" configuration (single channel\port only) on the DME
and SNS with 5.2.1 and have it working? Have you ever got the DME working with SnS 5.2.1
Thanks!
T.
