Try projectx. It works for .ts files but I'm not sure about .mts. Subtitle Edit is good for OCRing them.

I tried testing the output in subtitle edit and it looks rather flakey alas.

RE: DVB subtitles

I wrote a simple tool that can extract DVB-T subtitles from MPEG-TS and OCR's them with a Tesseract engine 3. Results are not perfect, but recognition can be improved with training Tesseract for specific font. Unfortunately that is quite complicated process. You can find this tool

RE: DVB subtitles

I believe you have hard subtitles :) some call them burnt-in, in other words the subtitles are part of the image, that also explains the other issues you have reported. There are tools that "extract" hard subtitles, but you have to test them yourself, on your particular file you have, see videohelp for a list of them.

RE: DVB subtitles

Can you upload some samples somewhere ? Some transport streams are missing PAT and PMT tables or interval of these tables is way to big and whitout them it doesn't even start searching for subtitles. I think that some tools exists that can rebuild these tables.

Clip 1: http://filecloud.io/4hqpwmz1 Crashes after pressing Start (but is detected ok). Clip 2: http://filecloud.io/eqf6rm09 (this is around 100mb into file, I just cut smallest possible clip for upload) Subtitle with PID 1050 is not detected. PID 1027 is detected but it is empty.
