The player is a LG SuperBlu BH200. Audio is passed to the DMA via optical SPDFF.
All audio passed through the SPDFF seems one quarter to a half second out of sync. Audio from the analog L/R jacks are in sync. A standard DVD player is normally used via the same SPDFF input on the DMA and has not shown any sync issues.
On the BluRay player, the audio output options are "Primary Pass-Through", "DTS RE-Encode", and "PCM Stereo".
When Primary pass through is selected, and a standard Dolby Digital track is present, the DMA automatically lights up for Dolby Digital with Descrete decoding. If DTSHDMA or DolbyTrueHD is present, all lights on the DMA go out, and no decoding takes place.
When "PCM Stereo" is selected, the DMA automatically lights up for PCM with Pro Logic decoding, regardless of weather the dsik has Dolby Digital, DTSHD, or Dolby TrueHD.
DTS Re-Encode causes all the lights on the DMA to go out for obvious reasons.

LG's Blu-ray players have never been considered in the top tier for performance or features, so I would recommend looking into replacing the player with something better. LG and Samsung have some of the worst reputations for quality and reliability among Blu-ray players.
As someone who is most likely interested in giving his customers the best possible picture and sound, the new lossless formats are a gift, not a curse! For less than $500, you can upgrade your source device so that you can access those high definition soundtracks to go along with the high definition picture.
I don't know about pro-grade Blu-ray players, but Panasonic is coming out with the DMP-BD55 that has all the latest and greatest specs, as well as 7.1 channel analog audio outputs. The Sony BDP-S550 does as well, I believe.
I don't know how suitable these players are for your specific situation. Since you probably don't need the BD-Live functionality, you may be able to track down the previous gen models as well (just make sure they decode both Dolby TrueHD and DTS-HD Master Audio to the analog outs).
Amazon has the Panasonic DMP-BD55 on pre-order (10/28) for $400, and the Sony BDP-S550 is $400 as well.
Personally, I don't think it should matter whether you are showing movies on 35mm, DVD, or 8mm. You are showing movies in a community experience with the added value that you can provide over and above what people can experience at home. I applaud your desire to deliver the best experience possible!
