Now first I will post the screen shot of the speaker setup menu.
As shown Panasonic has decided to use a completely odd way of implementing the delays.
First problem is there are no adjustments for the Front L & R speakers. Next huge problem is that is appears there is only ONE
adjustment for both the right and left surrounds (as well as surround backs). Of course instead of using length measurements you have to refer to a conversion chart to be able to use the tenth of a millisecond reductions they provide. If I am wrong and there is a way to adjust the R & L Surround independently, please let me know. I am going off the chart and how it appears.
The menu looks identical to what is shown in the DMP-BD50 manual so I am assuming the setup is the same. Can someone please go into their settings and see if there is a way to highlight the L surround and set a delay setting and then go to the R surround and have a different setting. If someone could clear this up I would really appreciate it.
I used the on-screen speaker adjustment settings ; shown in the above post and described in the review by Chris Boylen (see post #119) last night, with Ironman (Dolby TrueHD). I am outputting audio using analog 7:1.
The speaker settings allow you to:
1. Select either large or small speaker size for pairs of speakers(i.e. L and R are the same; as are RS and LS; and LB and RB)
2. Adjust delay times (ms) based on speaker distances (note: The R and L speakers are the reference distances; therefore adjustments are made to other speakers only, with LS/RS and LB/RB adjustments in pairs)
3.adjust speaker balance (dB) (note; all adjutments are negative adjustments only (i.e. 0.0 to -6.0 dB for the Front, 0.0 to -12.0 dB for LS and RS. Sourround back LB/RB speakers will default to LS/RS settings)
4. Run audio test signal to listen to speaker volume levels (dB); to aid in adjustment ( note the white noise is NOT output to the subwoofer. You must listen to an actual soundtract. stop play; make a guess for subwoofer level adjustment; then play to sountrack to verify adjustment; then repeat until suitable).
While admittededly awkward, the BD player does allow for speaker adjustments prior to sending audio output. This is important if your receiver does not allow speaker adjustments (e.g. LFE volume adjustments); when receiving muli-channel analog inputs.

I did not hear any sound coming from the surround back speakers; unlike Mr. & Mrs. Smith (DTS-HD MA). Is Dolby TrueHD a 7:1 format?
