Serviio + Macbook pro + Panasonic Vierra = cannot read file?

Since I got my mac I have been wanting to watch my computer videos via my Panasonic G25's DLNA for a bit now. I learned unfortunately that it isn't quite as a simple as with a PC, and I discovered Serviio as the best solution.
It worked pretty great without me really knowing what I was doing too, everything set up pretty easily, and I was able to see my computer on my Vierra DLNA menu and see the one video file I have so far with ease (an .avi accessed quickly via video then folders). But when I hit play on the TV it gives me the error "cannot read file." I can even see a thumbnail preview of the movie, so it's odd for me to come so close and be denied.
I tried googling this issue (since it's what led me to Serviio) but I am having a lot of trouble understanding a lot of what I've read.
Could someone make this real simple and give me step by step instructions on how to fix this? Since I've seen a bit on profiles and the like but I really don't understand how to make the proper edits to get this to work properly. But again, I have come so close, outside of the video actually playing I was impressed that it showed up thumbnail and all without any problems from Serviio unpacked and running.
So yeah, again, some very straightforward help on that last step (getting the file to actually play) would be sweet
