I do as well. I don't want to run W10 servers or Linux or do this anywhere but play on the LG TV from the LG TV. I have 12 TB of NAS storage in folders by media type and by month, year, decade, and century. (about 125,000 pictures scanned and digital) and about 1/2 the content is video movies and some instructional stuff. I want to access the NAS folders (PLEX or the version I have does not seem to do this intuitively or its too cryptic for me to figure out)
As another mentioned VLC would seem to work but we need a WebOS version and I don't see or can find one. One shodl be able to just Open a file on the NAS box and load it and play.....just like VLC does on W10 and even Android. etc.
Three items. 1) Content on NAS file system, 2) LG TV on the network with WebOS, 3) the missing link or software video player?
