I'm trying to use MeGUI to transfer a DVD to my iPod. But I'm having problems with the audio. I rip the DVD with Decrypter and frameserve with DVD2AVI and demux the AC3 track. I then queue up the ac3 track into MeGUI and set it up to convert to AAC/MP4, but when I try to run the job I get an error. Here is the log:

Anyone know what the problem is?
