This seems to be a symptom unique to the 203,and it's buffering and processing for upconverting/deinterlacing HDMI input. I've never seen it on my 103 which I've used with 720p/1080i HDTV input via HDMI for six years. Could be due to the extra work needed to upconvert to 4K (2160p) which is at the heart of this.
When I feed the same 720p/1080i HDTV input (i.e. my DVR output) to the 203, and repeatedly use the "skip forward 30-seconds" or "skip backward 12-seconds" control to navigate past commercials, or put the DVR into "fast-foward" mode to play past a TV program segment I'm not interested in, what gets delivered to the Oppo in rapid sequence are frames which are "discontinuous" as far as the onscreen image. This is very different from normal 30i or 60p frame delivery where each consecutive frame really is just a tiny bit different from the previous frame, making it "easy" to interpolate between video image data on consecutive frames. When this smooth progression of frames is radically disturbed by "skipping" through discontinuous image data on consecutive frames I believe the Oppo's buffering and processing logic is very much bothered (seemingly moreso than the same logic on the 103).
Eventually, what appears on the display screen is this "stuttering" artifact as you describe it, kind of like "pulsing" of "every so often" images rather than the true rapid-fire sequence of discontinuous (or even continuous, when normal speed playback on the DVR is supposedly restored) frames we know are coming from the source device feeding fast-forward or frame-skip to the Oppo. In fact, even after stopping the fast-forward or commercial-skip breaks source stream, ordinary regular motion program data is also presented in the "pulsing" defective way.
Similar to the other methods mentioned above as the "solution" to get things back to normal, my own technique is to:
(a) STOP the source DVR momentarily to stop feeding program data to the Oppo,
(b) use the INPUT button on the 203 to navigate from "HDMI IN" to "BLU-RAY PLAYER" and press ENTER, so as to force the "buffer flushing" of whatever damaged frame information is currently being absorbed and processed from the external HDMI input,
(c) wait a few seconds with the Oppo's home screen main menu displayed, for things to stabilize on the 203 NOT processing external input
(d) again use the INPUT button on the 203 to navigate back to "HDMI IN" and press ENTER, to effect a totally empty brand new buffering/processing handling for the HDMI input
(e) resume PLAY on the source DVR, and everything is once again normal with no "stutter"
I feed both Roku Ultra and DVR through my StarTech 4-to-1 HDMI switch feeding the single HDMI input of the 203, but haven't seen the "stutter" symptom from the Roku. But then I pretty much never am doing the kind of "commercial skip" or "fast-forward" I regularly do when viewing my DVR. However I suspect that if I did actually control the Roku the way I controlled the DVR that I probably would see the same symptom, since based on my theory its really kind of an "eventual overrun" of the buffering and inter-frame interpolation done by the Oppo as pertains to its upconvert/deinterlace of external input to 2160p output when "overwhelmed and confused" due to a rapid-fire arrival of completely discontinuous image frames from the source device.
