there are no modules with MLV in tab menu?

??
Maybe you should search on youtube, for some visual help on using magic lantern.
Don't know which build you downloaded, but if it's one from 2014 it should be something like this.
Turn on your camera.
Hit the "trash button".
By hitting the trash button you see the magic lantern menu
If you now scroll through the tabs in the menu, you'll see that there is one tab that has the title "Modules".
The tab Modules is just a simple list of modules available in you're build,.
As you can see in the Modules tab, the modules in the list are set to "OFF".
If you use the arrow key's you can go to specific modules in this list and by pushing the "set" button on your camera you can turn them "ON, will load".
This means they will be loaded by the next time you turn on your camera.
Now turn all modules with "mlv" in the name to "ON, will load".
Turn of your camera
Turn on your camera
Set your camera in video mode.
hit the trash button to enter the magic lantern menu
go to the tab with the name Movie (It's the tab with the movie camera symbol)
Go with the arrow keys to the option "RAW VIDEO(MLV) and set it to "ON".
Now press the "Q" button on your camera to set some settings you like.
Hit the trash button to get out of the menu.
Now if you hit the "start/stop" button on your camera, you're recording raw video !
