Do have a 1st generation ipod nano (the square, black or white ones) and have rockbox on it? and are trying to get videos on it but having trouble? Then this instructable has all the info you need. RockBox (rockbox.org) is an operating system developed for DMP's (Digital Media Players) that overwrites the original software on the device. The user interface is text based with jpg backgrounds. RockBox allows you to customize MANY more aspects of your device than with the original software: Audio: an extended graphic EQ with advanced audio tweaking. Photos: the ability to view photos of ANY size and res. by zooming in and out. Data: rockbox can allow our device to be used as a storage device (if it wasent already available) and you're able to view and manipulate any file on your device by way of a file browser. Plug-ins: Rockbox comes with a multitude of plug-ins ranging from color games (like a bejeweld knock-off) to nifty animated and graphical screensavers to diagnostic and testing apps. Themes: Rockbox has the ability to change the ui by way of themes, (background, text font size and color) There are a couple of themes included with rockbox, but you can download many more from the site. And there are many more features. Go to Rockbox.org to find out how to download, and what devices are supported. THIS INSTRUCTABLE is for the 1st gen ipod nano ONLY. Rockbox doesn't work on the 2nd gen (same size as the1st gen but it's in colors and it has rounded sides) Or the 3rd gen (the new one thats smaller and wider, it plays videos out of the box) This instructable is specifically for people that are firmilliar with rockbox and have a 1st gen and have rockbox on it, and are having trouble getting videos to work.
