Hmmm, I think I have to offer a different perspective on resolution here. For television output, I don't know of any monitors that are higher than 1080 pixels across. So if you scan at lower resolution, it should be ok. TEST it to be sure, but I'm pretty confident on this. If you are projecting the images, there are VERY few that are above that resolution. (I just did some images at 1000 pixels maximum dimension for a slide show. Even enlarged to five feet across, they were gorgeous onscreen.)
Tradeoff: If you're going to spend time correcting the images, adjusting color/brightness, removing red-eye, cropping, etc, before the show, then YES, scan at higher resolution--you'll need the pixels for corrections.
I normally do scan at highest possible resolution, but if you're trying to scan a lot of images in a hurry, speed is of the essence. Just don't PRINT from lower resolution images.
