Hi Lucy;

I am seeing just one :

multicasttech-2>show ip sdr "UF-ILABS-test"
SDR Cache - 250 entries
Session Name: UF-ILABS-test
Description: c:\ThunderAssets\HD-underwater.mpg
Group: 226.1.1.3, ttl: 64, Contiguous allocation: 1
Uptime: 06:44:45, Last Heard: 00:00:01
Announcement source: 128.227.74.138, destination: 224.2.127.254
Created by: - 49217374 0 IN IP4 128.227.74.138
Phone number:
Email:
URL:
Media: video 2010 UDP 0
Media: audio 2010 UDP 0
multicasttech-2>

By bogus SDP standards, this hardly seems excessive.
