I have loaded a DVD using Totem and verified that the "m" key works as described in the manpage (and in the "Keyboard Shortcuts" help menu). This is on a Debian Stretch desktop, using a commercially-manufactured DVD (i.e., with CSS protection). Conversely, when a DVD was not yet loaded, the "m" key (and all of the other alphabet keys) caused a search window to appear, pre-populated with "m". This matches standard behavior of many "explorer"-type programs, which present an interface for searching through a library of items -- videos, in the case of Totem. Did you try pressing "m" when a video was loaded? One of my test DVDs took a while to load while the system was "retrieving" CSS keys (as indicated by a message on stdout).
