Yep - Kodi in its current form doesn't output interlaced content as native interlaced (there are good reasons why). When you enable deinterlacing then content is deinterlaced (either to 25/29.9Hz frame rate or 50/59.94Hz field rate - the latter gives fluid motion on native interlaced content). When you disable deinterlacing, the output is not interlaced, but instead the player just skips the deinterlacing process and outputs the frames largely untouched, but as progressive (so you get combing on native interlaced content or 3:2 23.976Hz stuff) as it shows the two interlaced fields weaved together.
There are two approaches to deinterlacing on Kodi :
1. Hardware accelerated deinterlacing (where on modern platforms you get a decent motion compensative deinterlace). This approach is great on low-power ARM and Intel SoCs and uses minimal CPU load, but needs decent hardware decode and deinterlace support both in the chip(set) and within Kodi for that chip(set).
2. Software accelerated deinterlacing (usually coupled with software decoding of the codec) which uses just the CPU to decode and deinterlace the content. SD content (480i/576i) takes far less CPU to decode and deinterlace than HD (1080i). 720p TV content isn't interlaced so doesn't need any deinterlacing (there is no 720 line interlaced format). Kodi implements a reasonable YADIF 2x deinterlacer as its standard CPU deinterlace mode. For 1080i content this can take a significant amount of CPU (though newer ARM SoCs often have enough power to do so, as do modern Intel SoCs - though many Atoms struggle)
