I have some SD content ripped from standard widescreen DVDs. QuickTime has two aspect ratios 720 × 480 (853 × 480). Now, I know the content is widescreen, so it must be 853 × 480. Then, why does it also display the square aspect ratio of 720 × 480?

In any case, ErsatzTV is broadcasting this media in the square aspect ratio instead of the content's natural widescreen ratio.

Please show the media info from ETV (there's a "Show Media Info" button for each episode on the season page).

Also, please show the ffmpeg profile that the channel is configured to use.
