I record European TV programs using a TechniSat Digit HD8-S receiver. Playback is fine using the receiver and teletext subtitles (page 777) can be displayed. When trying to edit the .ts files on VideoReDo (6.60.10-816) however the subtitles are not displayed, despite the fact that the Program Information says that they are present. (see attachment). Is there a quick fix for this?
