It sounds impressive but Pocket DVD Wizard can reduce 4 DVD's to just 512MB in size without losing a great deal of quality.
This is great news if you're going away fro an extended period of time and want your favourite movies with you. The program works with both standard Pocket PCs and high resolution 640x480 VGA Pocket PCs. It allows you to select the image quality that you are satisfied with and watch the converted video in full screen mode without "letterbox" style black bars above and below the picture. The developers claim that it also works with Windows based Portable Media Center players, such as the Creative Labs Zen PMC or the iRiver PMP-120. This includes Windows based Smartphones such as the iJam and Motorola MPX handsets. Apart form the impressive compression ratios, what strikes you immediately is the ease of use of this program. There's very few clicks required to compress a DVD and it works pretty quickly compared to similar efforts. The fact that it supports to many output devices also distinguishes it from the rest - it can output to anything from a Pocket PC to an iPod or PSP. I also like the fact that it allows you to highly customise the ripping process, if you choose to, so that you can remove unnecessary files such as subtitles and extras.
There's not much to fault with Pocket DVD Wizard - if you like your movies on the go and have multiple devices, then you should look no further.
