Two questions about Multicast

Two questions about Multicast:

Question 1. Router with two network adapters for IPTV.

/ip address
add address=129.109.1.22/24 broadcast=129.109.1.255 comment= IPTV \
disabled=no interface=ether1 network=129.109.1.0
add address=192.168.0.1/24 broadcast=192.168.0.255 comment= Lokal \
disabled=no interface=ether2 network=192.168.0.0

/routing igmp-proxy interface
add alternative-subnets=135.17.21.17/32 comment="" disabled=no interface=\
ether1 threshold=1 upstream=yes
add comment="" disabled=no interface=ether2 threshold=1 upstream=no

IPTV via IGMP-proxy works. Bur now there is a new task – to transmit IPTV on the other router. As far as I understand, I should use PIM. I delete IGMP-proxy settings. Config PIM:

/routing pim interface
add interface=ether2
add interface=ether1 alternative-subnets=135.17.21.17/32

/routing pim rp
add address=192.168.0.1

After that I reboot the router. Here is log:
07:14:22 system,info router rebooted
07:14:26 pim,info Added new address to interface register: 127.0.0.2/8
07:14:26 pim,info PIM interface started: register
07:14:26 pim,info Added new address to interface ether2: 192.168.0.1/24
07:14:26 pim,info PIM interface started: ether2
07:14:26 pim,info IGMP interface started: ether1
07:14:26 pim,info IGMP interface started: ether2
07:14:26 pim,info Added new address to interface ether1: 129.109.1.22/24
07:14:26 pim,info PIM interface started: ether1
07:14:28 pim,warning RX PIM_BOOTSTRAP from 129.109.1.1 to 129.109.1.22 on v
if ether1: sender is not a PIM-neighbor router


Herewith in the PIM interface disappears letter «R». As far as I understand, I can not use pim in my net? Is there any way to solve my problem?

Question 2. Is there any opportunity to broadcast IPTV (multicast) PPTP or PPPOE for users? I can add these interfaces (PPTP, PPPOE) in IGMP-proxy or PIM, but IPTV doesn’t work.

Tell me please, PPTP or PPPOE users (win 7) can watch IPTV through IGMP-proxy or PIM? Or is it fundamentally impossible?

You say you wish to broadcast on other router...
What is the config on this other router.

Should it not also have pim setup?

I will answer myself to my question:
In order for PPTP or PPPOE win 7 users can watch IPTV, you need to install updates from the Microsoft website. This applies to Win 7 and Win Vista.
You say you wish to broadcast on other router...
What is the config on this other router.

Should it not also have pim setup?
To experiment, I used this example
http://wiki.mikrotik.com/wiki/Multicast ... ed_example

In my case, I brought the set «Router A». Interface ether1 (129.109.1.22/24) looks to the provider. When you configure this «Router A» in the log gives me:
07:14:28 pim,warning RX PIM_BOOTSTRAP from 129.109.1.1 to 129.109.1.22 on v
if ether1: sender is not a PIM-neighbor router

and 129.109.1.1 - router provider, and to him I do not have access.

I «Router B» have not yet set up so that Router A has given this error.
