I'm in the process of converting my DVDs to MKV format, and the subtitles are important to me. I'm currently using VobSub to rip the subtitles directly from the DVD, then converting to SRT format. When I look closely at the timecodes of Battlestar Galactica Season 3 DVD 5, all the times from the IDX files seem to be like this: timestamp: -00:42:27:880, filepos: 000000000 timestamp: -00:42:25:160, filepos: 000001000 timestamp: -00:42:21:800, filepos: 000002800 timestamp: -00:42:17:040, filepos: 000003800 timestamp: -00:42:14:560, filepos: 000004800 timestamp: -00:42:10:680, filepos: 000006000 timestamp: -00:42:07:040, filepos: 000007000 Am I doing something wrong? How can I fix this?
