Here’s a quick tip that I was pleased to discover. QuickTime Player has, for as long as I can remember, never been able to export the audio from an MPEG1 video file. It can play it fine but if you convert to something else such as iPod, you got a video without audio.
I used to have to use MPEG Streamclip to rip MPEG1 to iPod as it handled the audio properly. Last night, for the hell of it, I tried it with the latest QuickTime Player (7.4.1) and lo and behold, Apple has finally fixed it and I have my video + audio iPod track! Very nice, even though it’s taken many years to come to this.
