If you are bitstreaming audio to the Denon, the first thing I would do is change to LPCM output via HDMI: many reports of audio dropouts with various titles via bitstreaming are fixed when using the player to decode to LPCM.
It is my understanding that seamlessly branched files can have audio overlaps, where the audio on one file extends beyond the video of that file. I have no idea why this is done (apart from maybe a type of buffering during jumps between files), however it should be handled by the player. My suspicion is that maybe this is not handled well in all cases when bitstreaming, but for some reason is better handled when decoding in the player (maybe because audio decoding is performed in the player chip synchronously with video decoding). It is interesting to note that eac3to will remove the overlaps when merging seamless branched files into a single file, so it is obviously of concern for contiguous uninterrupted playback.
It was rumoured that Oppo might be able to revert a player back to previous firmware for a maintenance fee. It was also rumoured that some pro mod chips could force a firmware reversion, but that this facility was no longer available with more recent player firmware. I suggest you contact Oppodigital to see if the first rumour can be substantiated.Edited by IanD - 11/21/12 at 4:22pm
