Panasonic DMP-BD10A "LFE BUG"

by dsskid - 4/28/08 6:41 AM

I have a Panasonic TH58PZ700U plasma, DMP-BD10AK blu ray player, and Sony STR-DE875 receiver, and SA8300HDVR. I've hooked up both the cablebox and blu ray player directly to the plasma via HDMI. Since I have an older AV receiver (5.1, non-HDMI), the blu ray is hooked up to the AVR by both digital coax and multi-channel rca. I've set the codecs to: DTS - bitstream. DD - bitstream, TrueDD and DTS-HD to PCM.

When I play standard DVD's and set the AVR imput to digital coax, the sound blows you out of your seat. However, when I play blu rays, and set the AVR to multichannel, and set the blu ray player to BD video, HDMI audio, and downconversion to off (as directed on AVS Forum), the sound is not as good as when I play standard dvds, even though the BD10A decodes TrueDD and DTS-DH.

I know that the BD10A suffers from the LFE issue where HDMI, digital coax, and optical outputs results in a 5% decrease in LFE to the subwoofer, but analogs are supposedly uneffected. Anyone else experiencing this? It disheartening that I'm receiving less "Wow" sound quality with blu ray discs than SD DVD discs.

I've thought about upgrading to a newer AVR with an HDMI imput, that could also process TrueDD and DTS-HD, but it since the BD10A has the LFE bug over HDMI, it seems like it would be fruitless. Any thoughts on what to do?
