When we speak of watching videos on the DS, the first thought that often comes to mind is the Moonshell organizer's media player. While it gave the DS the ability to play video, converting the files (and their accompanying subs) was anything but easy.

Now, if you're dead serious about trying to find another video solution for your handheld, you may want to take a look at this application developed by Chishm, dubbed Tuna-viDS. This application will enable your DS to play AVI files that use XVid encoded video and MP3 encoded audio - two very common file formats.

Here's the lowdown on Tuna-viDS' file formats:

• Video: 256px wide, up to 192px tall, up to 12fps, XVid encoded, non-interlaced
• Audio: Mono MP3
• Container: AVI with chunk index, video must be the first stream (fourcc 00dc)
