If I understand this right, HDV is either 720p or 1080i video that is compressed on the tape with MPEG-2, correct?

How in the world can nonlinear editing software (iMovie, FCE, etc)work with HDV? Wouldn't it be messed up because of all the interframe compression and the key-frame thing?

Also, how much quality is lost with the MPEG-2, as opposed to DV25-type thing.

It is a Mpeg2 stream but it is different from the regular ones used by other sources.

I got mine today and I can verify that iMovieHD will NOT import any Mpeg2 HD transport streams that are not from the three HDV cameras...here is the error message I get...

Could that not be because of some copy-protection? Maybe to keep us from importing copywrited MPEG-2 files off of DVD's.

This was not from a DVD...this was a "copy-free" HD stream from an OTA tv station...
