nescafe,
1. i got my unit from WATSON PHOTO SUPPLY which is across the side entrance of SM Manila/Quiapo Carriedo branch. i got it at 4,800pesos. I was told to keep the receipt for a six month warranty. Watson Photo Supply has a good reputation in their trade, so i am sure when he says six months, he means it.
2. although Watson Photo supply did not specifically mentioned "any pioneer service center" as authorized service center for the nextbase, he did mentioned that after sales support for the unit is available because there exist a local service center for that brand.
it was when i went shopping at virra mall in greenhills last sunday, walked along second floor and saw NINTENDO selling the nextbase (at 4,850) and their "in house" brand ELECOM, who told me that both units/brands were serviced by PIONEER service centers nationwide. In fact they even explicitly posted their claim in the poster you will see hanged atop these players they sell.
gud luck. so far so good pa rin ang NB. only "all the president's men" pdisc has not played, but neither did it played in promac dvd2002 and sast aep816.
