I did call oppo after submitting question to audiogon, and if you do have the latest firmware on the 103 there is a sync delay in the audio processing page ,oppo have said the normal range falls into the 60 to 90 setting. Have tried it and it definitely works, so to mdempster this solved my issues,thanks to everybody's response.I very much appreciate your input.
Trouble with audio video sync
I hooked up a oppo 103 to my rotel 1068 preamp processor using the analog cables, since the rotel does not have hdmi,my problem is that on some blu ray music videos and some movies the music or sound comes slightly ahead.so far have reset oppo to factory settings, made sure the video is off on my rotel,but still have the problem, so I hope somebody out there has a solution. Would gladly try anything.
