I took the easy way out with the upgrade on my BDP83. Had the CD firmware update sent to the house.
Let me say Oppo's customer service seems to be as courteous, and problem free as Outlaws'.
Called them up to ask a few questions and in two to three days received the disc.
No problems. However for some reason I had to repeat the upgrade a second time.
I have to say that I am not as computer savvy as a lot of people on this forum seem to be. I do wish that I was not intimated about these upgrades. As of the writing I still have not done the upgrade on the 990.
I hope Outlaw makes the upgrades for the 998 as simplistic as possible for people like myself. The idea of a disc for the Oppo upgrade was great.
If I do pull the trigger on the 998 I certainly will take my time making the decision.
