Hi, I just happened to be wandering around the list of apps on my Roku 2 and found that Mezzmo has an app there now! Awesome! Thanks very much, folks!

A few things that I found:

a) Initial loading/locating my mezzmo server was a little slow - took maybe 10-15 mins. I'm on a wired Cat5e network, so I don't think network would be an issue. PC is an older machine running Windows 10 - not the slowest in the world, but not blazingly fast.
b) Click on MVI movies simply made a 'Roku noise' and returned without playing the video. It could be transcoding, but it wasn't apparent.
c) When I navigated to a folder of pictures that had about 350 items, the app hung at loading. (could have been caused by b)
d) It would be nice to have a looping mechanism for pictures (for slideshows).
e) It would be nice to have the option to play music during slideshows.
f) This might a DLNA limitation, but it would be nice to pre-fetch the next song in a list so that you don't have the pause of the next song loading. I know there is the Gapless option, but it would be nice if Mezzmo did it for me.

That's it, for now.

Thanks again!
