Ever since YouTube went HD earlier this month I have been trying to figure out how to get my videos to not playback choppy. I tried different video and audio bitrates. I tried different everything...except one setting. My sampling rate was set to 44.1kHz...not the 48kHz DV video norm.

SD videos apparently aren't affected (I've been using 44.1 for a while now) but if you upload an H.264 video with 44.1kHz sampling rate you will probably have stuttering, glitchy, choppy playback. Hopefully with this post I've saved some of you potential headaches!
