First off, I'm not sure this is in the forum, or if it belongs in "General Software", please feel free to move it if so, and apologies in advance. I recently bought a couple of harddrives for my NAS, after a very long time not really having any space to store movies or other files on. Thinking that I finally had a lot of space, I thought it a great idea to download 4k movies. Not knowing anything about formats, requirements and what have you, this turned out to be a dumbass move on my part. So I'm now looking for some guidance from some of you clever folk, to maybe solve at least some of it, or at least finally realise it might be absolutely impossible for me. I have several problems. My movies are stuttering, and I can barely watch a couple of seconds without them buffering. I'm using PLEX, and I honestly find the whole settings interface difficult to navigate, probably due to having absolutely no knowledge about this. I have en LG TV, and both with and without the PLEX app on the TV, it buffers. I realise there's most likely some transcoding issues going on, but I really have no idea how to figure out exactly if that's the (only) issue. I know for a fact my NAS is NOT able to transcode 4k movies though. And before you say I just answered me own question, I would amongst other things like to know if there's a way to limit the transcoding needed, and lessening the strain on the NAS. My TV is unfortunately only able to be connected through WiFi, but my NAS is wired to the router. My second issue is that since I downloaded all these awesome higher quality movies, all the subtitles are in PGS format. I need advice to some, preferably, freeware programs that can either change them to SRT in the MKV file, or something that can at least reliably extract and convert, and then I can remux it into the MKV file myself. I realise I can probably Google a lot of this stuff myself, and believe me I've tried. But it seems to be an overwhelming amount of knowledge I need to Google to be able to grasp what the hell is going on. That being said though, if there are any amazing guides to all this out there, something a dummy like me can understand, by all means, throw them my way.
