I do not need to watch the video to know what it is.
GMO files are PSP (most likely Dissidia) models, and can be viewed using Noesis Model Viewer (Google is your friend) and exported in OBJ. If you want specific models you can PM or email me (or add me to MSN) I'll gladly help.
NOTE: While I am not personally against imported models, this forums rules ARE. So, while I will help you doing it, I won't help you distribute it by any means.
Another thing worth of note is that, when it is your first time, a single model import can take hours, and even days (it took about 3 days for my frist model, and it wasn't anywhere near perfect) but no one is the same. Note here that I'm talking about CUSTOM models, not ripped ones. There is a huge difference between the two.
