I muxed a H264 video and a DTS audio file into an MKV container using MeGUI. Then I converted the MKV to VOB using MKV2VOB allowing me to stream to my PS3 with DTS. Unfortunately this video requires some subtitiles. I am trying to Demux my VOB so I can add subtitles and go through the whole process of placing back into MKV container with Sub then using VOB to encode the subtitles. I tried using HD-DVD/Blu-ray Stream extractor in MeGUI to demux into a .H264 video file and a .ac3 audio file. I added the subs and remuxed using MeGUI to add subs into a MKV container. I used mk2vob to encode subs and the video turns out ok but I get static for sound. I tried the always transcode DTS option in mk2vob but same result nothing but static. When demuxing the VOB file there is a drop down box that allows me to choose the format under the column header "exctact as". Under description colum for the audio file it reads "RAW/PCM, 2.0 channels, 16 bit, 48khz". The extract as defaults "AC3" but there are 9 formats to choose from. Should I use choose a different format other than the "AC3" Any ideas how to add subs to the VOB file.
