Worked out a new procedure which seemed to work reliably in deploying the new images to the Audi displays:

Wipe current content and reset settings for each TV

1. Power on TV, select MagicInfo source using remote and/or wait for current slideshow to load
2. Press Return button on remote
3. Select Options in the upper right of the screen
4. Select Delete, select Published Content, confirm
5. Press Return button on remote
6. Select Options again in the upper right of the screen
7. Select Settings, select Reset, confirm
8. Press Return button on remote till you get back to the MagicInfo Player S3 main screen
9. Select Network Status in the lower right portion of the screen, verify that the TV reports that it is connected, make a note of the IP in the event you need it for deploying content later

Deploy content via MagicInfo 2 software

1. Remote into DeltaNetMgmtPC, copy new images to the MagicInfo Content folder on the desktop
2. Launch "MagicInfo Express 2" as Administrator
3. Click Quick Start, Slideshow
4. Select the new images for the slideshow, click the > button in the upper right corner to proceed
5. Delete the text box containing "Audi Grand Rapids" in the upper left corner of the slideshow (click, press Delete key)
6. Run the preview to verify all the images and transitions look correct, click >, enter a descriptive name
7. Verify the schedule adheres to showroom hours, click the disk icon on the upper right, save as the same name you set for the slideshow
8. Click the send button on the upper right corner (square with an arrow icon)
9. Select all TVs to deploy to, if any are missing verify the TV is powered up and connected, click Add Signage TV, enter the IP address
10. Click Send
11. Verify new slideshow is operating correctly on all TVs
