here is something that might help guys , i wrote it on another forum
i am one of those people that wants my pocket Pc to do everything , even though its getting on now and not cutting edge , so for months i have been trying to squash down DVD movies to fit my 128 Mb Cf card
impossible you say .....no not realy , its just a matter of knowing a fair bit about compression and conversion and also having the time and patience , to read and read and read about the various ways of achieving the conversion process
Untill now , i stumbled across a bit of software on download.com called pocketDVD and to my amazement , IT WORKS ,

, the trial version only allows about 6 Mb of a dvd to be converted but the full version although a bit querky works great , no more hasstle of working out bit rates and sizes and everything else , pop in your dvd select a name to save it as , screen size , language and click start , hour or so later and its done
you can even select what size you want the file to become , i went and bought a 256 Mb Cf card because the bigger the file size the better quality the movie , and now keep my 128 Mb Cf card just for Navigation , oh and the odd , dodgy movie clip to impress my mates at work

, hey it`s the buildings what do you expect
just for reference i`m using a Ipaq 3630 so if you want to try putting movies on your pocket pc , use PocketDVD , and no i dont work for em , just like the software that actually does what its supposed to do , easily
the others above gave me loads of probs , and i`m using a fast and modern Pc , try them first please then try PocketDVD , i wont put link in here prob not allowed , just do a search or look on DL.com as mentioned in my txt above
i have found that cartoon movies are the best like Monsters inc and the such but normal movies are plenty good enough
hope this helps
