G/day Mark,   Sorry for this late reply, im getting on in years, and my memory isnt what it used to be, this paticular post had slipped my mind,and ive been stuffing around with the settings. Do you use the equalizer at all, or any enhancements, eg dolby ect. That swooshing sound i was talking about comes and goes, its hard to pin down. Ive looked at the TSS site and there is nothing on sound settings, what they give you in their sound packages, is not detailed enough, and i have left a suggestion to give a detailed description on sound settings. Anyway Mark thanks again take care      Jeff :)
