Hi
If so, what is a good HD DVD o purchase?
On what do You intend to play the HD DVD ?
No standard DVD-Player can playback HD-DVD only a few very rare Toshiba player were made to be able to use this very rare format.
All DVDs from Hollywood or iDVD - is same and only interlaced SD-Video - It's DVD Standard.
The quality on Your DVD depends on several things.
• file format (video codec) delivered to iDVD
• video editor used to create this Export file
• way it was sent to iDVD
• brand of DVD used
• type of DVD used
• burn speed on DVD-burner
An if You persist on HD-Quality then You need to do a Blu-Ray disk one way or another.
To do this You can use Your Mac and it's DVD-burner for very short BD-DVDs - BUT
• Standard Macs can not play these - nor Blu-Ray Disks
• You need a BD-Player as a PlayStation 3 to view them
• You need Roxio Toast™ 11 Pro incl. BD-component to make them
• a DVD can hold about 20-30 minutes in BD-quality
• and a Blu-Ray-burner and disks - If You want full Blu-Ray Disks with several hours of material.
Still I create my SlideShows in FinalCut and burn them with iDVD and get a very good result
iMovie'08 to 11 - can not deliver 100% interlaced SD-Video over to iDVD but discard every second line resulting in severe quality loss
Sharing to iDVD - from any iMovie versions also results in severe quality loss.
From
iMovie'08 to 11 - I "Share to Media Browser" and as LARGE (Not HD or other resolution as this too degrade the quality)
iMovie HD6 - Just import movie icon into iDVD - best possibly result
FCE/P - Export as QuickTime movie - NO QUICKTIME CONVERSION ! - and not self contained (not important but saves time)
just some thoughts
Yours Bengt W
