Hi, Trying to have Plex play back an mpeg2ts file (through a plug-in), and the startup (or seek forward) is very slow (and I mean VERY slow … ;)). I have a feeling it’s because I’m not setting all the needed parameters - I say this because of the following in the server logs, Aug 23, 2015 20:56:53:127 [4536] DEBUG - Request: [192.168.2.64:60199] GET /video/:/transcode/universal/session/1ysbo587rmos/base/index.m3u8 (3 live) TLS GZIP Aug 23, 2015 20:56:53:127 [4536] DEBUG - Found session GUID of 1ysbo587rmos in session start.

Thinking this is the problem (0x0 dimensions), but I could be wrong. Any pointers on this? Has anyone else had this issue? Thanks! ---
