Clonemobile When to Deinterlace?

Using Deinterlacing increases file size and minimal Bitrate. I’m trying to decide when it is really necessary? From My thinking it’s mostly TV Material but not all TV material. In the past I’ve gotton Herky Jerky Encodes corrected by De-interlacing. Some TV Shows looks just as smooth with it than without it. So is there a rule of Thumb here?

The best way I found to detect if the content is interlaced or not is load the VOB file in DGINDEX and press F5. The right window will show informations of video content including if it is interlaced of film.

And I assume I only use De-Interlaced on the ones that don’t say Film
