Tom,
Let's start with no ip directed-broadcast:
This instructs the router to not forward packets that are destined
to a directed broadcast address. For example, a broadcast is 255.255.255.255
in IP terms. In the case of 192.168.1.0/24, the directed broadcast address
is 192.168.1.255. Hence the router will not propagate packets to this
address.
Now for no ip mroute-cache:
This instructs the router to turn off cache support for multicast
packets. Basically is the same as turning off route-cache for unicast
packets and instructs the router to process switch multicast packets.
