Important: This is not a router firmware.
I'm trying to mod a Digital Video Recorder, h264DVR.
I'm aware that this tool wasn't coded exactly for this kind of situation.
But perhaps you might help me?
What steps will reproduce the problem?

What version of the product are you using? On what operating system?
Please provide any additional information below.
I can get the script to work once I manually unzip the .bin file.

I'm not sure how to proceed on repacking it, since build-firmware will always
result in a .bin file (I guess I need an .img one?)
Sorry for the newbieness. ._.
