Doesn't both routers have to have a RP (since you are in PIM-SPARSE)? On
your router r1, it doesn't have a the RP. Also, R2 should have the ip igmp
join-group 224.2.2.2 statement too.
You may want to see what groups each router has joined, but using the "show
ip igmp groups" to see which groups your routers have joined.
Also you can verify where each router thinks the RP is by using the " sho ip
pim rp mapping".
As another check, make sure they have made neighbors by using the "sho ip
pim neighbor".

Subject: ip multicasting and ping
For all you multi-cast wizards out there, I have 2 routers configured as
such:
r2 cannot ping multicast 224.2.2.2-4 on r1's e0.
Any reasons why?
Thanks,
Steve
