I use my 103 to feed my Panny 65VT50 in 1080p resolution, upconverting my TWC/LA cable-provided HDTV which of course is 720p or 1080i. Output from the 103 is via HDMI-1 where the QDEO video processing is, and the picture on the 65VT50 from HDTV is superb.
I suspect that you, too, will notice a visible improvement in 720p/1080i source program picture quality coming through the 103 when processed and upconverted to 1080p by the 103 via HDMI-1.
Are there any handshake or audio issues?
There appears to be a lip-sync issue with external HDMI input, which Oppo is aware of but so far has not resolved. The exact conditions producing the symptom are also not entirely clear or precise (adding to the difficulty of solving the problem).
For me, the lip-sync problem only occurs when I feed both downmixed-to-stereo audio out on HDMI-1 along with video, feeding my AVR which supports my 2.0 speakers as well as delivering video to my HDTV. But if I send "LPCM multi-channel" audio-only out via HDMI-2 (to my external multi-channel headphone system) and video-only out via HDMI-1 to my AVR and then out to my HDTV, there is no lip-sync problem.
Recently I accidentally discovered that if I changed the video output on the 103 to specify YCbCr 4:2:2 (from AUTO or 4:4:4) that the lip-sync problem seems to disappear. It's been two days now running this way, and no lip-sync has returned. I know this appears completely irrelevant to the audio lip-sync issue, but for me it seems to work... so that's how I've continued to operate. Fingers crossed.
Nevertheless, Oppo is aware of the lip-sync problem tied to using external HDMI input.
Is the STB set to 720p or 1080i?
You want to keep the number of conversions, interlace/de-interlace, and format changes to a minimum for best image results.
If your HDTV (on the other side of your 103, either fed directly via HDMI from the 103 or through an AVR) is 1080p then you would like the 103 to do the upconversion of source resolution to 1080p output resolution. It will do the best possible job if you feed it "native source resolution" of the HDTV program, i.e. converting 720p to 1080p or converting/deinterlacing 1080i to 1080p. That's necessary, but minimal, and your results will be optimal.
You do not want a 720p program to be upconverted (and interlaced) to 1080i by the Dish receiver, and then feed that interlaced 1080i from the Dish receiver to the 103 for a second upconversion and deinterlacing to 1080p.
So if the Dish receiver has a "native" setting, where it automatically just passes through 720p source as 720p output, and 1080i source as 1080i output, so that the 103 will do the one-and-only conversion to 1080p, that will give you the best results. Otherwise my recommendation (which is what I do) is to manually change the output resolution on the Dish receiver to either 720p or 1080i depending on the source resolution of the particular program I'm watching, so that as with "native" no unnecessary and unwanted conversions take place in the Dish receiver but only once in the 103. That's my recommendation.
