I just did a quick scan on current support and found these 
for the CRS and ASR9000:

http://www.cisco.com/en/US/docs/routers/asr9000/software/asr9k_r4.2/multicast/configuration/guide/b_mcast_cg42asr9k_chapter_01.html#concept_DDFFD955C56946EA8A640A680FFEB6EC
http://www.cisco.com/en/US/docs/routers/crs/software/crs_r4.2/multicast/configuration/guide/b_mcast_cg42crs_chapter_00.html#concept_DDFFD955C56946EA8A640A680FFEB6EC

The documentation on the ASR1000 is not the full suite, just 
mLDP without BGP C-multicast. Not sure when support is fully 
coming to the ASR1000, but last time I checked, it was meant 
to be 2013.

There was some internal tussle between whether BGP C-
multicast was coming in IOS XR 4.x or 5. Since I'm not 
running any IPTv services now, I'm not tracking this quite 
as much, although it is something we're getting Cisco to 
commit to for when we need to move video on the network.

p2mp RSVP-TE support has been supported on the CRS since IOS 
XR 3.9.0, and I used it with a Juniper edge (with major but 
fixable inter-op issues) in IOS XR 4. 

The ASR9000 got p2mp RSVP-TE in IOS XR 4.1.0, but I haven't 
run it on that platform. 

Mark.
