Some observations:I can't seek in media files on my Samsung 40C750 tv. It's play or stop. Nor can I control the seek position from Helium. This might have nothing to do with Helium nor with Rygel, but I do notice that Helium doesn't show the duration of the video - strangely, the tv does.
A setting to define the maximum volume. Currently the volume slider goes from 0% to 100%, but 100% is QUITE LOUD on the tv. An option to limit the range to e.g. 25% would be welcome. (Thus, volume slider to max exuals volume of tv to 25%). That way I won't annoy the speakers, my ears, the neighbors and have easier and more precise control.
