Transcoding to acc

Hi
I'm new to this.
I have a LG 47LE550N TV and I try to watch DVD converted with MakeMKV. But my TV just support H264 video and aac or DolbyDigital audio from mkv files. So I try to transcode to a mpeg container with mpeg2video and aac audio. But the transcoding is not working. I get from log:

When I run the ffmpeg I get:
encoder 'aac' is experimental and might produce bad results.
Add '-strict experimental' if you want to use it.
What do I do wrong?
