While watching in ff1 (double time) mode the screen will dim every 4 to 5 secods. This is caused when the "show commerical breaks" setting is set to sow commercial breaks. When I disable this feature the screen does not dim and it plays back normally. I would like to keep this feature on... so my question relates to the possibility of changing the what ever timer is involved to a longer interval. In other words if the screen only dimmed once in 30 seconds or so it would not be as irritating.
