I just bought an AppleTV 3 to replace a 1st gen ATV. I have a number of videos (all SD, no HD) that were encoded using the Handbrake AppleTV preset. Is there any reason I should need to re-encode these for ATV3? I took a quick look at a handful of videos and they looked fine. However, I just wanted to make sure there won't be any issues playing these on the ATV 3.
