My Sound and Vision calibration disc has both Dolby Digital And DTS test tones. Does it matter which one I use to set speaker levels? Will there be much difference? Thanks.

I would trust the AVR test tones/auto calibration (you didn't answer my questions as to what AVR you have) over the S&V disc. Don't forget, DD uses dial norm and DTS doesn't. This can result in a 3-4 dB difference in levels between the two systems.

I have the Insignia NS-R5101HD receiver. The Room EQ set my fronts to large, so I changed that to small. I am using HDMI. The reason I asked my original question was: Do different sound formats have different decibel level outputs? (Dolby Digital, DTS, and the new HD formats). And I was wondering why the cal. disc had DD and DTS on it. I want to know what to use so it sounds good with all formats. Thanks.
