I'm currently trialling your excellent Splash Pro Ex. I'm posting it here because I don't think it releates to any of the Ex features.
The recordings I'm viewing are MPEG2 .ts files made by the Humax PVR-9300T (SD) and HDR-Fox T2 (HD) STBs from the UK DVB-T Freeview.
Splash Pro does not seem to recognise the presence of the subtitles stream within the .ts wrapper, as the subtitles menu item on right click is greyed-out. The subtitles stream is definately present and can be displayed by VLC from the same file.
I have any number of examples of ~1Gb size, which I could FTP up for investigation if necessary (please provide relevant instructions).
Thank you for any assistance you can provide.
