GS748T v4 cross VLAN multicast routing

[bzyku]

I have a ProSafe GS748T v4 L2 Smart Switch. The main reason to get it was it's routing capabilities and Multicast. Where do I find information on how to setup the cross VLAN Multicast Routing on the switch? I need to deploy Chromecast devices VLAN accessible from multiple VLANs (dev, guest, office). I want the Chromecasts to be visible by dev, guest & office but I specifically do not intent to allow to cross-communication between dev, guest & office on the switch. I have a router dealing with that.

Unfortunately I have to describe the available documentation of to the more complex features of the switch as poor at best. Describing functions of the buttons is not enough.

Do I have to enable IP Routing to get the Multicast Routing running or are these separate cases?
Do I have to create a virtual IP Router on the device or are these separate cases?

Would there be a HowTo available as has Cisco done for their devices at: http://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/7-6/chromecastDG76/ChromecastDG76...

Does anyone can point me into the direction of a HowTo?

Thanks,

You can find most of these configurations here (not specifically for using chromecast, but might still apply):
