when downloading files to my ipad if the files require even the smallest transcode which plex optimized versions always do then if im download multiple files at once it will only download 1/3 to half the files and say the downloads are complete and i have to go to the downloads section and refresh for it to start downloading the rest but if there are alot of files it again will only download 1/3 to half of the remaining files and i have to refresh the downloads section over and over again until all files are downloaded. but this is only with files that doing any sort of transcoding.
most of the files i re-encode with handbrake dont transcode so they download fine. this is a problem because i usually download the night before because i dont usually have the time to do it before i go out.
if i use plex transcode to optimize my media they all do a slight transcode when downloading which means i have to keep an eye on it to make sure they all download
