I downloaded Rock Box yesterday because I found that the sandisk firmware was very feature challenged, After installing Rock Box and seeing that it is exactly what I was looking for I found that I could not open any of my pictures or videos, when before on the Sandisk firmware I could. Does Rock Box support formats other than .jpg and .mpg? If not then I think I will be forced to go back to the default firmware so that I can open my pictures and videos, : (. I was also looking for something that would support animated GIFs and flash SWFs, is there any way Rock Box can support those formats?
