Just come across this thread. I bought my Extreme sometime in 2004 for 3,400 (if I'm not mistaken). I was impressed by its feature although it was priced at the level of NextBase. It worked fine for the first 3 or 4 months, then it started to be choosy with the discs it plays. So I brought the unit to Raon Shopping Center where I bought the unit for repair. I was told that they'll bring me directly to Extreme's service center just on the second floor of that building, it turns out that one small dingy room was already their service center, inside it is one guy from PROC (CHINA) who can't speak any language except Mandarin who was the only person there during that time. He was actually browsing the internet when I went there. Inside the room was a mess of spare parts of dvds and several players stacked up in total disarray. He opens my unit, pull a set of lens assembly in one of the box that has piles of such parts that was just lying there, plug it in then give back the unit to me after having it tested. By the way, the reason why they brought me to the hidden 2nd floor repair center is that they thought I could communicate with the Chinese there, but it turns out that he can't speak Fookien but only Mandarin, so I also had a hard time talking to him.
However, seeing how he handles the parts such as throwing it around, not handling it properly, using trial and error from the parts from the open box that contain lens assembly (I don't even know if those parts were from replaced units or what. I am doubtful on the way/quality of the service. And as I expected, the repaired unit didn't last more than a month with me and it starts becoming too choosy again. At the end, I just give leave it for the maid to use - if they can chance upon discs that will play.
I would say, EXTREME is rolled out without proper QUALITY CONTROL, so it's a hit or miss chance if you'll get a good unit or a lemon. Good luck for those who will buy Extreme brand dvd, but for me, I'll stay away with this brand.
