HD .IDX subtitles to srt?

[oRBIT]

I've tried the new blu-ray ripping feature in DVDFab 7. It outputs subtitles in .idx/sub format and now I want to convert these to .srt. However, the regular .idx/sub subtitle ocr-tools seems to work quite bad with hd-subtitles.
I've tried a few tools for this but the OCR process doesn't seem to work as good as for DVD-subs.
So, can anyone give me some hints on what tools to use?

You could try this one: http://www.nikse.dk/se/SE-RC1.rar
Works best on a fast computer with lots of memory... uses Tesseract OCR ;)
Works best if MS MODI from MS Office is also installed.
