After calibrating home theatre speakers using SPL

[skularatna]

Some DVDS sound a bit low, and some are outstanding in terms of audio clarity. Does this just mean the audio encoding on the disks is poor? Or have i done something wrong with the calibration?

In my experience its been the disks but mainly on cheap dvd's or old films!

that's what i was afraid of. Films like lord of the rgins and my blu rays sound spectacular, the volume is a bit low on the smallville dvds... but that could also be down to the fact that its only dolby prologic II encoding on those discs.

AFAIK some of the earlier Smallville series boxes were only in Dolby Digital 2.0, though some of the later ones are 5.1.

So your receiver is trying to create surround sound that isn't there, which probably explains why the level is a bit lower. I'd try some of the other Digital Cinema Sound settings, to see whether one of those works better with stereo sources.
