Topic: 29.97 1080p H264 MP4 feels "less smooth" compared to 1080i H264 ts

Recently switched video sources and got mp4, then I noticed it isn't as smooth compared to .ts files, why would that be?

Thanks

More information needed.
- Your MP4 has XX fps and interlaced/progressive
- Your TS has YY fps and interlaced/progressive
