My Star Wars: The Clone Wars Disc 2 arrived! There were no questions asked and it shipped the next day! Hondo is the replacement disc (from the complete seasons set), sorry Ahsoka.
All in all, I’m pretty pleased with their customer service.
Call 800-553-6937 you can have your Star Wars: The Clone Wars Season 5 Disc 2 replaced with a disc with corrected audio. This will effectively fix the audio sync issues on disc 2. They did not ask me for anything other than my address.
