How to fix subtitles that are out of sync with video

[flexmcmurphy]

Hello,

I have a lot of DVB-S recordings made from satellite on an old Xoro 9000 box. The recordings are composed of several 1GB .ts files and I am using TSDoctor to combine them in to one .ts file.

I have come across one example where in the re-combined .ts file the audio and video are fine but the subtitles are out of sync. TSDoctor didn't mention or report any errors. What are my options to fix these out of sync subtitles? I don't think I can do anything else in TSDoctor?

Ideally I could avoid re-encoding the .ts file but interested to hear what the options are.

Any help much appreciated.
