It looks like the MenloMarseilles channel on Youtube has been nuked by copyright claims.
This isn't garunteed to be the real Hasbro though. We have seen Pensivepony get hit by this in the past, along with Masterlinkx. Youtube's flagging system is beyond exploitable.
It looks like most of the other pony video Youtube channels are still running strong.
Though if it WAS Hasbro, this could mean a Blu-ray set is on the way. I would be totally fine with that!
