    Just for a little heads up for those looking at new BD players, over at AVS Roger Dressler of Dolby Labs has just confirmed that the Panasonic BD10 and BD30 BD players plus the Denon BT-2500 BD Transport are running 5db quieter than they should be on the LFE channel over HDMI when reproducing PCM. This includes both straight PCM soundtracks and other codecs transcoded to PCM internally; bitstreamed codecs are unaffected. Right now he says that he is "not optimistic" that it can be fixed with firmware, but that it may be possible to raise the HDMI PCM LFE at the expense of the analog LFE - perhaps an advanced menu setting. From my own speculation, its very likely the $2k Denon also has this issue and a real possibility that the BD50 will have it, too.

    Let's hope it gets figured out. If you are a Panasonic owner and call tech support to open a case with this issue, it will probably get resolved sooner rather than later (if it can be resolved).

    Hopefully EVERYONE who owns this player and is using HDMI for audio will call and make your voice heard. This needs to be fixed!



    Also, cc: this guy in the email: Shiro Kitajima KitajimaS@us.panasonic.com

    He is President of the Consumer Electronics Division

    It is in everyones best interest who owns a BD30 and or BD10 and uses HDMI for audio to atleast drop a polite/profesional email to the Panny Cons Elect President explaining the issue, the current stance of Panasonic (which is that they are not going to do anything about the defect) and why we the consumer should not have to "deal with it" considering "it" is a manufacturer defect and should be corrected for at that level.

    Good news. Firmware 1.5 to be released tomorrow, fixes the LFE HDMI bug in the Panny BD-30 (but not the BD-10, that will require a different fix).
