Just an update on this one...
Since I can always easily change back and forth, today I implemented the suggested workaround for the "claymation video symptom" from the beta firmware, and changed the audio output from my Linksys DMA2100 (sent to rear HDMI input on the 103) to be 2.0 stereo rather than DD5.1. So now the 103 only sees 2.0 stereo always.
And sure enough, the video artifact symptom has seemingly completely disappeared. I've been watching TV for about 5 hours now (all 1080i programs), and never saw it once. Since I was working simultaneously, and thus listening through speakers the whole time (which would be downmixed to 2-channel stereo anyway by the 103 before going to my AVR and on to the speakers), letting the DMA2100 do the processing to produce the 2.0 stereo audio isn't an issue with me. The 103 is now simply receiving 2.0 stereo and no longer has to downmix it itself for delivery out the L/R analog outputs.
So this appears to be a 100% successful workaround for the video problem tied to the beta firmware. As I've stated before, since this was never an issue before the beta firmware (even though audio was still bouncing between DD5.1 and DD2.0 when coming from my cable DMA2100 to the external rear HDMI input on the 103), Oppo obviously must have done something to open up the new vulnerability which produced the artifact.
Anyway, video problem definitely temporarily prevented by limiting audio input via external HDMI to always be 2.0 stereo.
But, most importantly, I can also report that the more significant and long-standing "lip-sync problem" from external HDMI input that has been present on the 103 since product introduction... well THAT IS ALSO GONE, as I speculated it might be once using this all-2.0 workaround!
So for this 5-hour TV watching stint, using external DVR input from my DMA2100 putting out 2.0 audio, not only has the claymation video problem disappeared but there has also been zero lip-sync symptoms this entire time! That NEVER happened until now.
So clearly that lip-sync problem is also directly tied to whatever processing and handling is associated with DD5.1 (perhaps also involved with my downmix-to-stereo setting), and/or the transitions to DD2.0 and back as common when using DVR input for 1080i channels with DD5.1 audio and having intermittent commercials on HDTV bounce to 2.0 audio.
==> looks to me like the lip-sync problem can also be disappeared, if you change your DVR to output 2.0 stereo audio.
Obviously both of these issues should NOT be happening even with the DVR allowed to truly feed DD5.1 audio just because audio temporarily changes to DD2.0 and back to DD5.1, but hopefully Oppo will now be able to chase this down and fix whatever is causing both problems... for real.
