I don't know if this is relevant, but ffmpeg -i used to report

     Stream #0.3[0x25d](eng): Subtitle: dvbsub

and now it gives - obviously this isn't the same channel -

     Stream #0:3[0x69](eng): Subtitle: dvb_subtitle ([6][0][0][0] / 0x0006)

I'm not yet sure when the change occurred but think it's quite recent. 
Seems unlikely to explain a difference in recordings taken at similar times.
