I understand the problem of editing mpeg (and I've written about it
extensively, here). I don't know, however, how Premiere Pro handles HDV
(or, for that matter, mpeg with the MainConcept plugin). I've edited to
mpeg using the MainConcept plugin and can make frame-accurate cuts.
However, the clips need to be rendered, which suggests to me that Premiere
Pro doesn't convert to its internal format, as I understand it does with
DV-Codec AVI.
