IGMP snooping enables the router to block certain types of multicast messages to devices that the router thinks are not interested in receiving these messages. This is done to reduce load on the network in some high-traffic situations. For various reasons, the router often incorrectly thinks a device is not interested in these messages when actually it is interested. Disabling IGMP snooping tells the router to forward all multicast messages to all devices.

It is possible to get IGMP snooping to work correctly (I have done this on my own network) but this is much more complex than just disabling it.
