Problem with Dolby TruHD

[Pinto]

As more and more BDs are coming out with Dolby TruHD I am encountering a problem with audio. Some TruHD movies (Indiana Jones Crystal Skull for example) are playing along fine then there is a sort of hiccup or glitch in the soundtrack. If I rewind and replay that section it isn't there, so I know the problem is not in the disc. It happens only two to four times in the movie but it is jarring and now I'm kinda dreading it when I watch a movie with TruHD. There is no accompanying video glitch - the picture runs smoothly. This makes me think it must be in the audio decoding in the Onkyo. I am bitstreaming the audio from my player for the Onkyo to decode. I never have this problem with PCM soundtracks or DTS HDMA, let alone old Dolby 5.1.

This receiver has one firmware update that I know of - I did it a few months back to get rid of the DTS bomb (and it worked).

It is happening in about half the Dolby TruHD movies I watch, but seems to be coming up more often in movies that have just been released. Has anyone else experienced this or does anyone have any ideas what is up?
