Just came from a meeting with 2Go (formerly Aboitiz Express) representatives. Regarding sending DVD's, CD's, optical media, 2Go allows sending of these "even pirated" at regular package rates as long as it is well packed and shouldn't be more the 5 pcs (considered personal effects). More than 5pcs will be subject for investigation by customs.
Usually it is up to the outlets discretion if they accept or not.
