OV2500 Enterprise IP Multicast setting on AP1201H

Hello All, I am fairly new to OV2500 Enterprise mode. I have a question regarding the IP Multicast setting on AP1201H under OV2500 NMS. I have set IP Multicast on my OS6350-P24 switch port, and the IPTV video is able to stream as per normal but when I plugged in via AP1201H Port Eth2, I am experiencing stutter to the video stream. Is that some form of setting I need to add on my access profile in OV2500? If so, how can I set it?
