I had a problem with the door on my DV970HD in the first year and they fixed it and got it back to me within a week with no problem. A few years later the door is acting up again, so I'm questioning the build quality at this point more than the service.
Oppo customer service
Well, I had what turned out to be a known issue with my BDP-93 - it would not retain my wireless connection after it was set up. Oppo sent me a prepaid UPS label to send it in to them. Well, since they emailed me every step of the way, I could see that they received the unit at about 2:00 p.m. last Thursday, repaired it, and had it shipped back to me around 6:00 p.m., the same day! I received it the following Tuesday, complete with a new box and tote bag, all cleaned up and repaired. Couple that with the fact that I have never waited on hold to speak with an English-speaking customer service rep at Oppo, and I am totally sold on this company. I don't know when I'll be buying another disc player, but as long as Oppo is making them, it will be an Oppo player!
