I suggest two options:
1. If you are familiar with Windows Movie Maker, which usually comes with Windows Vista (C:\Program Files\Movie Maker\moviemk.exe), you can use it to make photo slideshow and burn saved WMV video with your favorite dvd burning software, say Nero, Roxio.
2. Choose one photo slideshow software to make slideshow and directly burn slideshow DVD for TV playback. I once use Wondershare Movie Story to make my travel slideshow DVD, and the result is excellent. I share my beautiful travel photos with my family.
