Very annoying music problem with slideshow

Question

I have been trying the whole afternoon to solve a perplexing problem when trying to set up a slideshow:
Initial problem:
When selecting one or more songs, using various methods such as directly selecting the song, using a playlist from iTunes or a "custom playlist" in iPhoto slideshow music settings, iPhoto for no apparent reason when previewing, simply restarts a song before it or the slideshow have finished. This is despite choosing the "Fit to music" option in settings.
SO
Second much more irritating problem:
I thought I'd see what would happen if I exported it. I selected two songs, and combined those songs using all the methods listed above as well as actually creating a new iLife preview song file in garageband and even exporting the two songs into a combined .mp3 file again with garage file. I must stress that when played in Garageband, in iTunes and even with iPhoto's music preview, the two songs play perfectly one after the other with no problems. However, no matter what method or indeed file combination I use, when exporting, iPhoto causes the first song to restart a few seconds after the second one has begun resulting in them playing at the same time which as you can imagine is pretty frikking annoying and basically makes it impossible to present such a slideshow. At first I thought it was "selecting" the first song to replay but it does this even with a single .mp3 which must appear to it to be only one song, so it appears that it simply restarts the track from the beginning at a random place in the slideshow, while continuing to play the track already playing.
Anyone else experience this - I have yet to try the delete, write to CD and re-import option but this seems like a ridiculous and unacceptable thing to have to do to get something so simple to work.
Any suggestions would be welcome.
Thanks

Try deleting the iPhoto caches in the your User/Library/Caches/com.apple.iPhoto folder and the iPhoto preference file, com.apple.iPhoto.plist, that resides in your User/Library/Preferences folder. Reboot and try exporting again.
I'm able to export a slideshow with 3 songs without any issues except that there are long gaps between songs. Lots of dead air due to the fade out and in of the tracks.
Question: Do you have the Quicktime Player 7 installed? It's an option with Snow Leopard installation. Also when the slideshow is being exported which icon do you see in the Dock, the older Quicktime Player 7 icon or the newer QT Player 10 icon.
For several reasons I've removed the QT 10 Player and use the 7 exclusively. It have more features and, IMO, does a better job at most everything. What I'm getting at is that if the QT 10 player is exporting the slideshow that may be the problem.
If you have QT 7 then zip the QT 10 player and delete the unzipped application. Then try an export to see if you have better luck. A long shot but might work.
Some more info about QT Player 7 and it's use alone can be found in this topic: UPDATE!.
