OK, so
StreamTransporter no longer seems to work, and while I haven't really used RTMPDump manually it would seem that this is the only way for me to get Hulu videos.
Right what I think my problem, Adobe copy protection.

Now I am using RTMPDump 2.3, HxD and Firefox to gather the link information. I had started the download while the video was still playing, also I tried pausing the video before attempting to download. Same resolute.
