Deinterlacing settings

Hi,

I have an odd issue with live tv (dvb-t uk tvheadend) that causes judder when set to auto, its like its switching between on/off every few seconds. The easy solution for this is to set it to default on for all video.

This means though that when I play a blu ray rip etc its going to be set with deinterlacing on. Is this going to cause any issues such as judder, blur etc or will kodi simply not attempt to deinterlace them evem though its set to on?

I know its a minor thing but it would be nice to not have to switch settings everytime I change from live tv to stored media. Any suggestions on the best way to handle this?
