I never adjusted my pot either. According to some forum that I forgot who I talked too....basically I have a Sony DVD burner which when it writes to my Ritek G04 the Gamecube says its bad, skips whatever. However I found a pack of Fuji/TDK+R's that work perfect. Now if I use my pioneer DVD burner with the Ritek G04 my gamecube reads em fine hence why I said finding your burner to media combination.
