The video quality seems perfectly fine in both cases, but I was
surprised to see that one download was more than twice the size of the
other, both being virtually the same duration and at the same resolution
and frame rate. I just compared recently downloaded episodes of The Fall
and The Missing. The audio in both files is 125kbps AAC, the difference
is all in the video. Both downloaded using --modes=hlsbest.

The Fall: 59m 30s, 1280x720, 50fps, video bit rate 1976 kbps, file size

The Missing: 58m 54s, 1280x720, 50fps, video bit rate 4549 kbps, file
size 1.93Gb
