I own a slingbox pro HD and a slingbox solo. When I am watching my slingboxes on my computer (through Firefox), the volume control is far too imprecise. Having a slider bar for what is technically a 0-100 value is very frustrating as I can never get the volume to be what I would like it to be. There are times when I am trying to increase or decrease the volume and the slider just does what it wants to.
Please, for my own sanity, add a number box to the volume control or make the slider bar more precise. I'd much prefer the ability to control the volume via a number box though.
