The GIGA MP3 function enables playback of MP3/WMA music files burned on DVD instead of CD. This means just one or two discs can be enough to store all the albums on your shelf. Why? Because the capacity of a DVD disc is much larger than that of a typical CD. The 4.7GB medium permits around 100 hours of recording, letting you store up to approximately 1,000 songs on a single disc -- equal to 100 pre-recorded CDs. GIGA MP3 ensures easy onboard access to all the songs you have -- with virtually no disc changes or no connection to external devices.
