Your video is for blender. The image I am seeing for your uv map appears to be an automatic unwrap which breaks things into lots of little uv islands like that.
You might want to find a tutorial on using maya's uv unwrap tools. The blender tutorial does show the proper places to cut the uv's. You just need to do a couple selections and projections that are not shown in that blender vid.
