We were going to use their CMS. It's Metrix Stream.
We backed off. It's way overpriced, triple the price of something you can find somewhere else. Too many tech needs to associate with it. Unless you have a highly skilled programmer to aid you, I would probably go with elevated x for cms.

It's kind of funny. XonDemand went with Metrix Stream. Once they went live with it, that's when they stopped paying. Metrix Stream is priced at about $1k+ a month.
We were going to do our VOD on it. Then we found out everything involved with the operation. We backed off really quick. Then we were going to run our cams on it. Again, same... we backed off even faster.
I'm not saying it's bad. There's just a whole slew of gadgets that go into play with it.
