NO HDDCD Problems here (yet):
For you gurus, I just received a REFURB BH200 that has a build date of Jan 08. I don't know if the build date makes any difference here. The out of box FW was BH02071119P/PKG411_LGZ, and the driver was 701.
I updated to the March FW (BH02080314B) via CD without incident. Thanks, gurus, for providing me with the links to this FW.
After updating the FW I updated the driver to 0702 via internet without incident.
In the setup I set all the audio settings to bitstream passthrough and sampling Freq. to 192 kHz. Of course the network option was available after the FW update. I set the video to 1080P (not 24 Hz). I left all the other settings to the defaults.
My receivers are the Denon 3808 and the 4308 which, as the above settings indicate, are doing the decoding for me.
I shoved in a few movies to check if I have any of the high definition audio problems:
NO Blu-Ray disks have any problems (DD, DD+, True_HD, DTS, DTS-HD, DTS-MA. The receivers decode all of the formats to their intended formats.
NO HD-DVD disks have any problems that others are having! This includes DD, DD+, True-HD. I played Spartacus, Batman Begins, and several other HD-DVD disks, INCLUDING TRANSFORMERS, and all of them are doing proper decoding.
I played Allegri Miserere, a beautiful chorale piece (music CD) "just to make sure" that even music CDs would work. An SD disk, Master and Commander also played standard old DD without a hiccup.
5.1 playback to ALL speakers is working.
I hate to say this but I agree that if there is a bug in the March FW update, it is due to the RECEIVERS (with the later Denons likely being the exception) not being able to handle DD+, etc., with the March FW provided by LG.
I saw on here that some other later model Denon users are NOT having audio issues with the LG.
This being said, I am GUESSING that LG used Denon receivers as their guinea pigs when they were writing the new March FW, because of the ability of the Denons to do the HD audio decoding via bitstream. I think that very few other receivers do the HD decoding. As a consequence when the FW was released the other receiver manufacturers started getting "OOPS, this doesn't work with our new FluxCapacitor receiver" problems! Of course the only thing LG could do was pull that driver as Denon is not the only popular AVR manufacturer.
Hmmm.... maybe that is why it has taken so long for both Samsung and LG to write HDMI passthrough drivers for the myriad of receivers on the market today.
It is not that the Denons are any better than other receivers; I guess I am just lucky in that LG wrote a driver that works with the Denons. Everything is working for me... so far.
