Thanks for this post. These settings seem to have fixed my Samba
configuration. I had configured with AIO previously, but apparently my
tunings weren't spot on. I'd get buffering over 100Mbit with 1080p
video, but 720p video would work just fine. Looks like this is what I
needed to be able to ditch using DLNA for streaming to my Popbox!
