I have often used Kinoma Producer 3 for converting video for playback on a Palm device, but now I am told that they have started to support Sony PSP. In other words, you can take your Alias shows and put them on your PlayStation Portable, in an easy manner. Even though there are other programs that do the same, but I don’t think there are any which work on both platforms, Windows and OS-X. It can convert AVI, DV, MPEG-4, 3GPP, QuickTime, and MPEG files, in addition to most other QuickTime compatible files.
