It's about doing random access in an MKV that contains cues pointing to non-video tracks, in this case pointing to an S_DVBSUB track. Those tracks are also not currently supported for demuxing.
As long as your scripts didn't use random access, e.g., they were processed linearly from the beginning, the transcodes will be fine. This is typically the case for a simple transcode.
