The thread title says there’s a avchd dvd9 version (which I suppose would fit on a dual layer DVD, so maybe 9gigs-ish) and an NTSC dvd5 version (which I assume fits on a single layer ~4.7gb DVD).
In all fairness, Harmy has been unable to change the thread title with the new forum software, so that’s actually still a reference to the formats available for the v1.0 release.
But yes, there are a few versions available, but are less ideal than reencoding to your needs from the best quality release, the AVCHD has a decreased bitrate to be, well, AVCHD compliant, the NTSC DVD-5 is DVD compliant (so understandably lower resolution and has the compression issues of MPEG2). The person responding about reencoding it yourself was probably meaning to be snarky, but it actually would be the best option if you want a good quality, more portable version for your own needs that are not tied to particular optical media standards.
