With iTunes, apparently, you can increase the buffer size "Large" to stop the frequent buffering that may curing when listening/watching videos/music/podcasts. I've never tried this, but they may have removed the latest version of ITunes. In any case, I'm getting this same problem, but on AppleTV 2. It could be a coincidence, bur of all the times it keeps re-buffering is on shows (ie pod cats) that have been released the same day. I have a feigning maybe the "Large" versions (when available), may/may not always solve this, but I cannot find a link to this concept. The different is their a larger file size, but that looks about it, (based on the length of time they go for). Anyone else have this problem? Presumably, it would also happen in the ITunes application itself too since it's coming from the same source.
