Why dv & dvcpro to p2?

Another significant change was from DV’s metal-evaporated tape to metal-particle. Metal- particle tape

Why didn’t we check here earlier?

It would seem recording in the DVCPRO 25 option with the HVX200 onto P2 that the extra 2 tracks get written as well. Obviously the MP over ME tape selection wouldn’t matter nor would the track pitch but the audio scrub track and the color lock-up track are written into the signal and make up the difference in the DVCPRO spec.

Quote from Adam Wilt’s page: “Panasonic’s DVCPRO increases track pitch and width to 18 microns, and uses a metal particle tape for better durability. DVCPRO also adds a longitudinal analog audio cue track and a control track to improve editing performance and user-friendliness in linear editing operations”.

Well, I don’t think the camera will record longitudal _analog_ audio track to p2…

Btw, I believe that PAL dv & dvcam has 4:2:0 because designers thought that PAL has enough more lines than NTSC to give it better horizontal chroma resolution. This is also quite nice when outputting to dvd, because mpeg2 is 4:2:0 also. (That might be also reason why you don’t get so good dv->dvd in ntsc and so there has been quite a bigger need for dvcpro50 & digibeta to get a good quality dvd in ntsc.)
