Hi there Im not sure if I actually posted your file back by email..
Simple answer : HDV mpeg2 1080i
Longer: ahem..

My understanding is that AVCHD was meant to be a playback format t which combined high quality Hi def with small size, on a Non tape medium
It has done that and more as it has spawned the next generation of camcorders
However editing was an afterthought from the looks of it
Also live HDV the output for domestic payback was not given much thought
However HDV has the advantage that software could generally output edited HDV back to tape, playable on any HDV camcorder ( not brand specific)
With AVCHD, the situation is a bit different
AVCHD editng software did not take of for a long time and some would say it is just coming of age .in some ways the mac worls is ahead there
Also AVCHD editing did not seem to have the output back to AVCHD as the primary goal
The output was to mpeg2 1080i ( HDV) or WMV-HD
Both of which can look good but wmv-HD is mainly PC based
There are Quicktime HD and Divx HD files too
Blu Ray and the now dead HD DVD support h.264 9 AVCHD, mpeg2 1080i ( HDV and VC1 ( a subset of WMV-HD)
So in theory Blu ray discs can be authored with any of them as input
AVCHD seem to be a "standard" but the codec are not identical which is why some software will support AVCHD from Panasonic but not Sony and Vice versa
Its not all crystal clear ATM

Currently it seem SVMP8 does support 1080p but not from Sony but not Panasonic camcorders and the Canon 25(f)p does not work with it
