I export QuickTime slide shows with a 4- or 5-second space between
slides from iPhoto and use Toast to burn SVideo movies of these slide
shows with music I add in Quicktime. The problem is that very frequently
the SVideo CD movie has a flash that occurs every .5 seconds.  The
flashing doesn't start until about 15 or 20 minutes into the SVideo.  If
you advance the video one frame at a time, you find that the flash is
caused by single frames that are created with low resolution graphics.  
The images on the blurred frames are composed of a bunch of squares of
color like blurred photos on TV.  My slide shows made into SVideos are
usually 20 to 35 minutes long.  I use either a mp3 or aif sound file and
attach it to the QuickTime mov file.  What could be causing this?

Photos with very little detail don't show the flash since a low res
digital version looks about the same as a high resolution version. On
the other hand, photos with thin stripes exhibit a lot of flash since
the blur of black and white stripes is a gray square.

It happens with either the Apple SuperDrive in my iMac G5 or the
external Que CD burner. It also did it in my b/w G3 with the Que CD
burner.  The QuickTime mov file looks perfect.  It isn't until Toast
creates the SVideo that the problem exists, so I assume it is a Toast
problem. It happened with Toast 5 Titanium and occurs with Toast 6
Titanium.  Again what could be causing this?

I guess I will try some RW CDs and try some variations:

Control) Export mov slide show from iphoto.

Variation 1) Export iPhoto photo sequences and open the sequence of
photos in QuickTime PRO and create a slide show in QuickTime PRO.

Variation 2) Try to use an old version of Toast.

Variation 3) Make a regular video CD, not SVideo.

Any other ideas?
