I looked at the original source file and there are only two streams; one audio and one video. What other reasons would explain the drastic difference in file size? You can download the original source video from http://static.playonsports.com.s3.amazonaws.com/example_expected.mp4.
You are quite mistaken. There are 6 streams in that file.

Can RTMPdump be configured or modified to record these additional streams?
rtmpdump records what the RTMP server sends. Nothing less, nothing more. I'll say it again, one last time: none of what you're asking about has anything to do with rtmpdump. Go talk to whoever provided your video data.
