Lightroom 5 does not allow slide playback less than 1.0 seconds in the Slideshow module. In LR4 you were able to adjust slide playback down to 0.1 seconds, this was great for photo sequence videos and now you can't go below 1.0 seconds. Adobe, tell me this isn't so, love that I can now add videos to my slideshows but it no longer works for photo sequence shos. I hope this is a bug or something left out if not PLEASE add this back in at the next release!!
