Louis,
Ip igmp profile filters IGMP membership reports. In this case, R4 is
sending PIM joins to R2 not IGMP membership reports. Do a show ip
igmp member on R2 and you probably won't see any of your groups listed
under E0.
If you want to test igmp filters, move your ip igmp join-groups to
R4's Fa0/0 and turn off PIM on R4.
