Convert to MP4 or DNxHD codec?
Neither. It's a Standard Definition DV file (either DV-AVI or Quicktime-DV, depending on what you captured it with). DV about the best available for working with Standard Definition interlaced footage. DNxHD is for HD footage (hence the name) and while there are hacks and settings that can make older SD footage work with modern codecs, there is no advantage, and only potential downsides. Stick to the native format.
If you have a firewire port, capture to DV. If you don't, google for local video transfer places. Most cities are going to have somewhere that will capture off the tape. Cost you $25-50 depending on the place. Bring a flash drive. Budget 13GB for every hour of tape.
Once you are done editing you probably want to export to a square pixel de-interlaced mp4, but whatever editing program you use should handle that.
