During Star Trek (2009), I noticed 3 audio dropouts with my Oppo BDP-83. I am using the HDMI output (Monster 1000HD HDMI cable) from the Oppo (which has the latest firmware update-9/30/09) to my Integra DHC-99 pre/processor. I have only experienced the audio dropouts with the Star Trek Blu-ray disc (the Oppo has worked flawlessly otherwise). The dropouts last about 2 seconds and as soon as the audio returns, the front panel of the Oppo reads "Dolby Tru-HD". I suspect this indicates that the BDP-83 lost and reacquired the Dolby Tru-HD signal from the disc. I contacted Oppo who told me to change my HDMI cable, that the problem is not consistent among their customers, that they have not been able to duplicate the problem, and that this may not be a firmware update issue but a problem with the disc it self. During a Google search, I found that several other BDP-83 owners have also experienced this problem with the Star Trek (2009) Blu-ray disc. The audio dropouts only appear to occur when sending the signal via HDMI and not through the analog outputs of the BDP-83 (which may partly explain why not all BDP-83 owners have experienced the dropouts). BTW, there were no audio dropouts with my Panasonic BD-55.
