Burn double layer disc image to a single layer dvd?

This might be a very stupid question, but let me explain my situation:

I have just under 1 hour and 20 minutes of 1920 x 1080 HD video exported from FCE (quicktime movie, not conversion) and imported into an iDVD project. I changed my project info to Professional Quality, Single-Layer Disc and chose Save As Disc Image, and the resulting file is under 4.7GB, able to fit on a single-layer DVD.

When I open the disc image file in DVD Player, the quality looks low-res. I know that there is some loss of quality for DVD compression, but I want to get the maximum quality possible for this project.

So, I went back into the iDVD project info, switched to Dual-Layer Disc, and the arrow indicating quality went towards a greener area of the scale (indicating better quality), but the file size stayed under the 4.7GB limit for single layer DVDs.

My question is this: If I Save As Disc Image at this point, would I be able to burn the resulting disc image to a single layer DVD?

iDVD '08, Mac OS X (10.6.8)

No. By selecting dual layer iDVD will not compress/encode the video as much thus giving it the higher quality indication. With dual layer selected iDVD will be looking for a dual layer disc when it starts the process.

Hi

There is a far fetched solution - but far from perfect.

(Best You can do is as Old Toad writes - Make it SL from start)

But anyhow

• in iDVD Save as a DiskImage

• Then use Roxio Toast™ and copy the DiskImage to a new SL-DVD - BUT also select Fit-on-DVD.

Now Toast will re-compress (takes sever amount of time) so that the material will fit (up to 10 hours on a SL-DVD)

BUT there are several Cons. to this

• Roxio Toast™ is not free - nor is it cheap

• Takes a long time to do

• Resulting DVD will look poor (Much worse than a SL-DVD from iDVD from start)

(A 10 hour SL-DVD - looks like crap)

So Yes it's technically possibly - But I can not motivate it at all.

Yours Bengt W
