As noted in our fifth-generation (with video) iPod coverage, several users are experiencing issues with synchronizing home-compressed video to the device. Many users reporting this problem are using the specified encoding option offered by QuickTime Pro 7.0.x to export the non-transferrable video.
In addition to this inability to create valid iPod-format videos for some users, a number of readers are reporting extremely slow encoding times for the MPEG-4 compression component in QuickTime Pro 7.0.3.
