I saw that the last reply to this question was at least a year ago. I am seeing support for a browse by folder in other media servers (e.g., TwonkyVision) and it seems to be supported in the latest firmware revision of my Roku as well. Are the prior limitations that prevented adding this feature now addressed?
No, and the real stopper is the roku side. It’s doable on the firefly side, but doesn’t make much sense if there isn’t a client to take advantage of it.
The roku forums would be the place to bring this up.
