Homesteader Droopy (1954) opening title music error
When this Droopy cartoon has been released on Tex Avery's Droopy: The Complete Theatrical Collection DVD release in 2007, for some strange reason the cartoon's NTSC Turner print has the opening title music used for the MGM Cartoons logo erroneously replaced, where it's original MGM opening fanfare is replaced by that of "Droopy Leprechaun" (1958). This audio error however doesn't appear on the PAL version of that DVD set though.
