Cisco Switching/Routing :: 6500 QoS COS Egress Not Marked

Problem: My traffic coming inbound appears to be marked but is not marked when egressing.

Setup:
Ingress from encoder G3/9->> Egress G8/1Default DSCP/COS map table (DSCP 24 is COS3) 
Cos-dscp map:
cos:   0  1  2  3  4  5  6  7
------------------------------------
dscp:   0  8 16 24 32 40 48 56
 
1. Any reason COS 3 is not marked outbound on this traffic? I'm determining this by doing a wireshark off of interface g8/1. The traffic appears to be marked on the ingress correctly but does not maintain its mark on the egress. I can confirm this with equipment on other Ethernet links in produciton as well as my test port listed in the config below with wireshark.
 
FYI: Unfortunately with my cards in the 6509 I cannot port mirror and see outbound multicast (determined through a TAC case). Because the STB does not understand tagged traffic I setup the native vlan for it to function. To see the multicast with tags I temporarily remove the native command and do the wireshark to see the multicast. It still shows a COS setting of 0. I will try to attach a capture of a multicast packet.
