Nintendo releasing a portable MP3 player DS and GBA upgrade in December

Last year Nintendo released the Play-Yan, a movie and MP3 player in Japan. This year Europe gets an optional MP3 player upgrade for the DS Lite. While it’s great that Nintendo is finally releasing the useful tool outside of Japan, Nintendo claims that this is only an MP3 player. In fact there is no mention of the Nintendo MP3 player being able to play movies on the DS Lite. Let’s see the Nintendo MP3 Player uses SD cards like the Play-Yan, it works in the Game Boy Advance slot also like the Play-Yan. Is this the same device? Or did Nintendo strip it down because it was difficult to convert movies to play on the smaller DS or GBA screen? At least the cost is cheaper, the Nintendo MP3 player runs at 30 euros ($38) while a Play-Yan costs $70 if you import it.
