I'm pretty sure you'll need to connect a Mac to it to project the slideshow, either as a movie or an iPhoto slideshows. I could be wrong but I'd call the venu and ask what's needed on your part to play the slideshow. Be sure to give yourself plenty of time to do what's needed.
What version of iPhoto do you have?
If you have iDVD you could create a slideshow in iDVD, burn to disk and play it via a DVD player if they have one at the venu.
xExport the slideshow out of iPhoto as a QT movie file via the Export button in the lower toolbar. For iPhoto 9.4.3 and earlier select Size = Medium or Large. For iPhoto 9.5 and later selct 480p.
Open iDVD, select a theme and drag the exported QT movie file into the open iDVD window being careful to avoid any drop zones.
Follow this workflow to help assure the best quality video DVD:
Once you have the project as you want it save it as a disk image via the File ➙ Save as Disk Image menu option. This will separate the encoding process from the burn process.
To check the encoding mount the disk image, launch DVD Player and play it. If it plays OK with DVD Player the encoding is good.
Then burn to disk with Disk Utility or Toast at the slowest speed available (2x-4x) to assure the best burn quality. Always use top quality media: Verbatim, Maxell or Taiyo Yuden DVD-R are the most recommended in these forums.
You can set the iDVD project to automatically play the slideshow when the disk in inserted into the player and have the slidsehow loop continuously if desired.
