… if I go back to using iMovie HD, can expect better results? …
in short: no
iMovie-a was by concept a dv-editor, supporting only tape-based media (later 'pimped' to import from HDV).
So, HDef content, esp. from, AVCHD, is of little use with iMovie-a, You have to follow an unconvenient manual conversion detour - only to get the same Intermediates as iMovie-b uses. (or less, using wrong settings, such as 'popular' tool Handbrake uses… )
according your 'quality' problem:
a) DVD is SDef only - a quarter of resolution of your original material
b) in iMovie-b, 'Export using Quicktime'/Options/Codec/Appleintermediate exports iMovie-b 'native' timeline
c) drag the resulting mov into iDVD; stay under 60min length, and you get max possible quality.
final word: judge final DVD-quality only on a tube television; any flat-screen TV scales DVDs = this could make content look worse than it is. If you use a wide flat-screen, read the players and TVs manuals to avoid any 'optimisations' which in many cases make things look bad If you playback Disks on your Mac, set the player window to DVDs original resolution = 720x480 - which is, again, about a quarter of res a computer screen shows.
iMovie-a was (or is…) only 'better' when using miniDV - it handles DV media natively, keeps format inherent interlaced, exports as DV - if you just perform plain 'cuts', iMovie-a exported a 100% of what you did import. Lossless, so to say... For HDef? Makes no sense.-
