.m2t not all get imported into media pool

Hi,
When I try to import a batch of .m2t files into Davinci Resolve media pool, only some of the files get imported. I then converted one of the files to an mp4 file in Handbrake and it displays in DR.
What is the best method to get these batches of files into DR? Convert all to mp4? Best settings? Handbrake or other?
And then I want to "up rez" the files; I have the REZ UP plugin, en hance and resize, or would RD be better at it?
The m2t files were originated in 2013 on Mini DV on a Canon HD40, and at the time ingested onto a Mac with firewire to m2t files. I now work on PC. I have the Mini DV cassettes.
Thank you,
Rina Sherman
