I tested a large number of players for another forum, with these favorites as a result.
1. BS Player -the most tweakable, least stutter, ability to pinch and zoom, and exit to pop-up. Lan access.
2. MX Player -the most supported codecs, including .wtv Lan through ES File explorer.
3. Wondershare -along with it's predecessor, Daroon, the only ones that would play ts_video files using the dvd menu. Lan access. Also has web video links, although they are titled by tv episode and not show.
Unfortunately, wifi throughput is not good enough to play uncompressed dvd and Bluray structure.
Maybe a usb solution can be found?
