No SOLUTION till DATE for this SCNERIO ???? Challenging

Hello ,
I have a Query to which no one have answered so far ??

PE2-PE3 are in AS20 and are MP-iBGP neighbor to each other.
CE1 and CE2 are two sites connected to PE2 and PE3 respectively talking
through the MPLS VPN cloud.
The multicast distribution trees are also configured and the Intra-AS
multicast end-to-end is working smoothly fine between CE1-CE2.

I have the below topology in which I have a trouble.

INT---------PE1--------PE2-------PE3--------CE1
                     | |
                     | |
                    PE4 CE2

Now,I have PE1 in AS 10 which is gateway to the internet and is peering with
PE2 for ipv4 (add-fam) only.
I have PE4 in (AS30) which is peering with PE1 for both ipv4 and vpnv4
(add-families)
PE4 is Multihop Mp-eBGP neighbor to both the PE2 and PE3.

PE1 is advertising the internet (0.0.0.0 in vpnv4 add family) to PE4 and then
PE4 is throwing it to PE2 and PE3
After manipulating the Next-Hop , PE2 and PE3 do watch the internet default
vpnv4 route 0.0.0.0 coming from PE1 and they do access the internet easily.

At this point when I check back the multicast between CE1 and CE2 , it will
stop working and the traffic is dropped
The momnet , I remove the 0.0.0.0 route adver in the vpnv4 from PE1 , my
multicast will run perfectly fine.

There is PIM running between PE1 PE2 and PE4 but no solution to the problem
till date !!
Can you please help me in this special problem ???
