Ok, it seems the last 350 firmware did *partially* restore 50fps.
I say partially because it only streams 50fps at Best HD with a 720p50 source. Previously, it streamed at 50fps at Good, Better, Best etc with a 720p50 source. The point I was trying (and obviously failing) to make was that this was very useful as the bandwidth at these resolutions, at 50fps, was modest, but the picture much smoother when watching sports.
Is there any chance that can be brought back?
Currently both 720p50 and 720p60 sources stream at the higher framerate when the quality is Best HD, I'd like to see both these sources stream at the higher framerate for lower quality settings too, just like it used to with 720p50 sources.
