First post on AVS Forums from the other side of the Pacific.
(1) As a universal disc player, the first thing I would like Oppo to include to is the ability to play karaoke disks. Both DVD-L or CD+G type disks. Unfortunately Oppo doesn't support this. Understand that karaoke is a niche thing, but it's very popular over in this part of the world.
(2) The second thing I'd like to see is IP controls and an app with the ability to easily import playlists from iTunes or easily create. The play based on locally attached storage or streamed.
(3) Tied together with the item (2) is the third wish of a visual jukebox interface that can browse / select music and movies. Easy search function instead of hunting through an endless list.
(4) Space provision for an internal 2.5" / 3.5" HDD. Cooling and noise maybe an issue, but it would be a neat solution for items (2) and (3).
