iDVD won’t complete burn + quality poor from disk image

I've used iDVD a lot over the years, and it’s always been straightforward and worked well. This time, though, I can’t get the DVD I want.

iDVD runs through all the stages as normal, until it gets to “writing lead-in”, showing 3 minutes to go. Then it ejects the disk, while continuing to show the progress bar with 3 minutes to go. I’ve tried 4 disks, and the same happens every time. I’m using Sony DVD-R, and have already used some disks from the batch with success - so I think they should be fine.

I’ve read a lot of posts on the forum, from people who’ve had similar experiences and I think I’ve tried everything - including working through the very useful long checklist from Bengt, here:

https://discussions.apple.com/thread/2238608?start=0&tstart=0

But the same happens every time, at exactly the same point.

So I produced a disk image instead, and burnt the DVD via Disk Utility. This worked, except for one important thing - the image quality is extremely poor. (All the source material is excellent quality and so are the movies when viewed on my MBP, eg. in both iDVD and Quicktime player.)

Can anyone offer any advice on what might be wrong, and how to fix it?

The DVD project is based on 2 Quicktime movies, and comprises the following:

1. movie: 12 mins, 5GB, 1280x720 (ProRes422)

2. movie: 2.20mins, 871MB, 1280x720 (ProRes422) created with PhotoPresenter and FCE

3. background image: 1.2MB, JPG, 3000x1868

4. audio for menu page: 1.7MB, mp3

I'd really like to get this one to work!

Mac OS X (10.6.6), 2.53 GHz, 8GB RAM, 500GB, 7200rpm,

Did you use Share ➙ iDVD in iMovie? If you did that may be part of the problem. That method only provides half of the information that is available in iMovie to iDVD, i.e. throws away every other line.

Use the Share ➙ Media Browser menu option and add the movie to iDVD via the Media/Movies pane in iDVD.

If you did use Share ➙ iDVD and try the Share ➙ Media Browser you should start over with a new project due to issues with iDVD trying to replace encoded assets with new assets in an existing project.

Hi Old Toad - Hate to correct - such a BesserWisser mentallity (and even more so when self is out on lose ground)

BUT

• Share to iDVD or Share to Media Browser - DO not (as I see it) affects the picture quality at all - may be even Share to Media Browser will be worse if HD-quality is selected - Due to BAD DownScaling to Medium Q

• The Loss of every second line in the picture - I learned - occurs when going from Event's to Project's and that's why there is no method to get it well again.

(But Raw material in Event's - I'm told - is still 100% interlaced SD-Video quality if imported as this e.g. from miniDV tape)

Yours well wishing - (and bad spelling) 😉 - Bengt W

Thank you. Not a smart aleck mentality at all. I learn something new every day here. I'm not much of an iMovie user so need to rely on the experience of others. I've only used iMovie 6 HD for my iDVD projects when I use movies in them. There's no substitute for iMovie 6 HD.

Have a good day and weekend.
