I am using a two-year old iMac with 10.4.3 installed, iLife 5, CanoScan 8400F, QuickTime Pro and Photoshop Elements 2. My harddrive has approximately 50 Gb of available space.
After scanning the photos, I duplicated, cropped as needed and resized the photos to maximum 655 or 480 pixels. I wanted to show the photo without caption and then transition to the one with caption so I duplicated the resized image and added a 0.35 inch canvas around the image. Then I added a 0.3 inch canvas to the bottom for the caption. After adding the caption, I resized the captioned image to the maximum 655 or 480 pixels. I found that if I did not add the border iMovie would not show the complete caption no matter what size I made the image.
If I used QuickTime Pro to make the movie from a slideshow created in iPhoto, the captions would all show without having to do all the borders and canvas changes. However, I would lose the capability of adding title pages. (Photos and sections of video are intertwined in the DVD.)
While creating the iMovie, I found that the captions became fussy/burry everytime the project was saved. If iMovie was closed and reopened, the fussy/burry captions became clear again. Go figure. Sometimes I had to do the empty trash-save-close reopen twice because something new would show up in the trash after the first empty trash-save-close-reopen process.
Also sometimes I would start to get stuttering/jumping images while checking music and images while in the Timeline Viewer. If I moved to the Clip Viewer the jumping would stop.
If I used RENDER CLIP when sending to the iDVD, the caption text became fussy/burry and the photos will have to be reinstalled in iMovie. I had to use PROCEED ANYWAY. The photo images appeared the same whether they were rendered or not. It was only the captions that changed.
I used Best Quality encoding for the final project. Best Quality actually took less time (about two hours less) burning the project than Best Performance. My final DVD is 26 minutes long with about 50% photos and 50% video. The caption text could be sligtly crisper but is more than readable for the family viewing. I did not experiment with different fonts to see which would be the best. (Getting to this point was flustrating enough and I was ready to see the project finished.)
I tried using the KB effect for rendering as mentioned in this thread but found it cumbersome to get the photo image timing where I wanted it and using KB did not improve the apperance of the caption text above not rendering when sending to iDVD. iMovie also crashed several times while working with KB effects. I did use some KB effects on some photos without text.
Maybe my experiences will help someone else who is working on this type of project.
