Even though my Panasonic display screen says "DTS-HD", it's lying. The manual says that it is actually just DTS-Core.

Liar, liar, pants on fire Panasonic!
But I think it sounded just as good as any TOP NOTCH PCM or TrueHD I've ever heard.
Oh, yeah, there were plenty of bass/drums coming very distinctly from my SURROUND speakers, which are set to LARGE. Interesting, but maybe not as important.
Since LOW LOW BASS < 40Hz is non-directional, I assume the bass I heard very distinctly from my surrounds was upper bass like 40Hz-100Hz?
