Most people still don't have BD burners (got beaten to it), so the AVCHD may be their only way to watch this in HD on their BD players na the encode quality is still very very high. And I think that if there's another SD DVD, it will be a DVD9, because this is very grainy and that doesn't agree well with mpeg2 compression.

I dunno, my opinion is that the whole point of a DVD downscale is to cover the lowest common denominator, and a DVD5 does that better than a DVD9 (media, layer-change issues, tech-savviness, etc). Also I actually think Chewtobacca's DVD5 downscale looked fine for SD (weird software playback glitches notwithstanding). I'm not really sure throwing more bits at MPEG-2 SD content would improve matters that much. I guess it's a bit early to argue that one though.
