Are you trying to process MPEG-1 files with QuickTime Pro? You can usually tell this by file extension, typicaly .mpg, or by looking at the Show Movie Info window in QuickTime Player, available under the Window menu.
QuickTime can play the sound in MPEG-1 files but it can't export it to new formats, like the iPod video format. Podner works around this limitation in QuickTime by relying on a third-party tool to extract the audio from MPEG-1 files. Unfortunately, our software is only for Mac OS X and will not work on Windows.
Does anyone here know of a good iPod video conversion solution for Windows? We've briefly looked at Videora iPod Converter, at
