I had audio drop outs for the first time while playing SIMONE on my Panasonc RP56. This is the only DVD to have an audio drop out.
I played the DVD on my laptop pc without a problem.
I played another DVD (Usual Suspects) on the 1050/RP56 with out a problem.
I switched from OPT 1 to OPT 2 and still had the problem.

The one interesting symptom I am checking into is: the 1050 DOWN MIX Indicator is illuminated with the SIMONE DVD and not the USUAL SUSPECTS DVD??? Both the DOWN MIX mix and DIGITAL Indicators blink off during the audio drop out. Drop out lasts for about one second and occurs fairly regularly at 80 seconds intervals. Is this a problem with the 96 kHz digital stream? I am going to see if I have other DVDs running with the higher data rate.
