Since there's no dedicated thread for this player I thought I'd start one. I'm currently comparing the Panasonic to the Oppo UDP-203 and so far the Oppo is lagging on both 4K UHD and 1080P Blu-ray playback. The DMP-UB900 is producing noticeably more detailed output on both sources. DVD upscaling, however, is sub-par on the Panasonic compared to the Oppo, which is just outstanding on SD material. I'm experiencing a problem with the Panasonic however. When I stream ripped Blu-ray titles from my Plex media server via DLNA I'm getting no audio, and the only audio stream the player is showing as available on this content is stereo even though my ripped 1080P stuff is in a MKV container with full DTS Master HD audio included. The Oppo has no such issue and I get full high-res audio from the same MKV files. I admittedly haven't scoured this thread, but does anyone have an idea as to what might be going on? If I can't get this to work the Panasonic will be going back despite it's slightly superior PQ. Thanks.
