I've been using Sony bluetooth headphones with Sony ipod adapter on my ipod for a long time, and now that I've got an iPhone I like the idea of watching music videos while running on a treadmill with iPhone in front of me, and using wireless bluetooth headset. Same goes for the movies and youtube. Unfortunately, there is this delay in audio encoding making bluetooth stereo with video basically unusable. I was wondering if there is a software which compensates for this delay and allows lip sync. Or it's just wishful thinking.
