KMDonlon,

I'm just wondering if there could be a internal issue with your 990 where reuploading the current firmware can fix. One main reason why I purchased the 990 was to replace my Parasound AVC-1800 surround processor which did not compensate for Dolby Digital and especially DTS subwoofer outputs inherent with these formats. I always had to manually decrease my subwoofer by 10dBs relative to my 2-channel use which is exactly what DTS does with subwoofer outputs. DTS always boosts subwoofer output by 10dBs for their standards. So I am thinking there could be an issue with the auto compensation feature in your 990 for the various formats. Maybe the original firmware in your 990 is corrupted somehow and reloading it again could fix it?
