Why do my videos play at twice the framerate?

I'd been using my old laptop as my "home theatre" for the past 4 years to watch movies and shows. I just got a new laptop a few weeks ago, and for the first time today I watched a TV episode on it (a local file saved on my secondary hard drive, not a streaming video). My first thought was, "The video looks like a soap opera." It looked good but at the same time strange. I'm guessing that the video was not playing at the standard 24 FPS but at 48 or 50 instead. Why is that? My old laptop had a GTX 670 MX card, but used the integrated Intel HD 4000 for general use, such as watching videos. My new laptop has a GTX 1070 that is connected directly to the display. The display is a 75 Hz display with G-Sync technology. I am playing videos on Media Player Classic - Home Cinema using ffdshow for video decoding. I only have sharpness enabled, and I am quite sure I am using the same settings as on my old laptop. Anyone have any idea what is causing this? Is this the way videos are supposed to look when playing on very good hardware?

An additional question: What is deinterlacing, and does that have anything to do with what I am experiencing?
 
Solution
None of your specs are close to your old laptop, of course it will look different, especially the screen running at 75 hz with Gsync. Deinterlacing is merging the alternating frames of the video into one frame.
