I have my sky+ box connected to the TV via scart and to a surround sound system via an optical cable (got to be done for the 5:1 benefit!!). 2 things/faults i've noticed: 1)If I listen to sky via the TV only, then there is a very apparent and annoying hissing sound. If I divert the sound through the surround sound system, then the hissing disappears. Obviously this is not a major problem as I'll just listen via the system, but if I didn't have that then I'd be mightily p'd off. Has anybody else experienced this and if so, what was the remedy. A friend of mine has suggested that this noise is to do with the digital sound from the Sky+ being converted back to an analogue sound for my TV and the noise is a resultant of this. 2) When switching the picture between Sky+ and the TV (using the SKY button and the TV button) on the Sky+ remote control, the picture quality changes. The picture when in Sky (AV1) mode is noticably brighter (not in a good way) than when on ordinary TV mode. This didn't occur with my last sky box. All feedback greatly appreciated.!
