The macroblocking issue appears to also effect some Panasonic plasma models. This issue apparently traces to the Faroudja processor in the 981. There is a long-running rumor that a firmware update for the Faroudja chip is in the works. I have not seen a trace of macroblocking on my JVC HD56FN97. I have also seen the specific warning about calibration on DLP sets. If you call Oppo and tell them what set you have they will recommend a player they feel is the best match rather than trying to sell you their flagship model.
