Telecined or not?

[Riptide]

Hi, mind helping out figuring what to do with this footage? Is it correct that it is telecined? It's from a BluRay which states 29,97 FPS. I think they just added the raw NTSC version to the BluRay. When I play the video I see 3 progressive frames, followed by two combed frames. All this interlaced and telecined stuff still gives me headache so I want to be sure what to do with this footage. Thanks!
