Interlacing and aspect ratio, in that order. Material made for television is interlaced almost without exception, so deinterlacing must be on or every moving edge arrives combed; and a large part of it is stored as non-square pixels with a flag saying how wide to display it, which a converter that ignores the flag turns into a stretched or squashed VOB. Check the first few seconds of the output before running a batch — both faults are apparent immediately and invisible in the settings.
