I'm a bit of an ATV noob, the only time I spend with one is trying to set things up for my boss. She's a professional photographer and currently manages almost a terabyte of photos in RAW format using Adobe Bridge (they're all on an esata RAID setup but that's not particularly important). She's got an ATV and a lovely 50-some inch Samsung LCD which she would like to be able to use to show photos off from time to time. The logical solution as far as I was concerned was to take her selections for a slide show from Bridge, drag them into iPhoto (had to upgrade her to 09, she was on iPhoto 5 which doesn't play nicely with NEF files). I've got her set up through iPhoto and iTunes to share her entire photo library. This works alright except for one thing... When she builds a new Album in iPhoto it takes sometimes an hour or more before that new album shows up on the ATV. Is this normal? She's thoroughly annoyed because she would like this to be a dynamic solution where she can create slideshows on the fly, but if she has to sit around and re-check the ATV every 10 minutes until it works, she's just never going to use it.
