I use PLEX thru my ROKU 4 box that has a sd card. I noticed that when I play any movie or tv show there is a delay as it shows a percentage loading and has to get to 100% then shows the show.
Any way to speed things up?
All my movies/tv shows are on my SSD hard drive and the network cable goes from the router to the ROKU box then using a HDMI cable to the tv set. Distance is under 10ft total cable length from router to roku to tv.
My guess, (for what it’s worth), is a SD card is usually much slower than an SSD drive and will load slower in the ROKU. I would try using a PC with an SSD drive to store my movies and cu the ROKU out. I’ve used a Rasberry Pi to serve movies and it worked OK. A ROKU is a pretty minimal device.
