Photoshop Elements :: How To Port Slideshow From PSE9 To PRE11

I currently have installed and successfully used PSE9 for a number of years. I recently purchased and installed PRE11 in order to do some video editing however I first created a slideshow in PSE9 with the intent to burn it to a DVD. The completed slideshow includes 140 still photos (all resized to 1000X750 maximum), transitions, text and music but no video) and when I tried to port it to my PRE11 using the "Edit with Premiere Elements" command, I received the following message "The feature you selected requires Adobe Premiere Elements" and then an option to download a 30-day trial. I did some research online and have read that different versions of PSE and PRE are not compatible and therefore I have the following four related questions.
 
1. is it correct that my PSE9 will be unable to port to my PRE11? And, if that is not correct, then how do I get past the above error message in order to burn my completed PSE9 slideshow to a DVD via my PRE11? I do not want to convert the slideshow to a WMV to created a CD due to the lower quality.
 
2. If it is correct that I cannot port between different versions of PSE and PRE then does any program I can use to take my completed PSE9 slideshow out of PSE9 and burn a high quality DVD of the slideshow?
 
3. If I have to upgrade my PSE9 to PSE11 in order to port my slideshow to PRE11 and thus burn a DVD of my slideshow, is there any way to move/copy/cut&paste my existing PSE9 slideshow to the new PSE11 or will I need to totally recreate it in the new PSE11?
 
4. If I must purchase and install PSE11 in order to do the above, is there any guarentee that the new PSE11 will allow me to port the slideshow to my existing PRE11?
 
Seems like an awful lot of work just to produce a slideshow DVD but I'm willing to do whatever it takes since I've already spent quite a few hours getting the PSE9 slideshow exactly the way I want it.
