Thanks for the post.
I followed your link and found the Vimu Video player app which is a $2.99 app.
I purchased it and installed it. It does find network shares, and will play video and music files. I didn't try a whole gamut of video file types, however. It doesn’t appear to find any pictures however.
It found all of my network shares, and I successfully logged into one of my NAS boxes. It did display all of the directories. However, the photo directories were empty.
If anyone is considering purchasing it, you should check out the supported file types/platforms at
http://www.vimuplayer.com/formats/
Since it wasn't included in the factory installed apps, I didn't include it as part of the review. Of course, the GTV platform is (somewhat) extensible, and it's nice to know that SMB capabilities are available from third parties.
It would have been nice if the included aVia app had included SMB capabilities. At least it played photos.....
