Yep I too got very frustrated trying to put movies onto my Clie! I HATED IRC!! I did not find it intuitive at all, and seemed waaaaay too confusing to use. Also I am sick of seeing posts with "matrix reloaded" trailers!!! How many matrix reloaded trailers can there be??? Seems every other movie that goes up is the matrix reloaded!!!
My solution: I download movies from:
http://www.pocketmovies.net/cat_8_0.html
-They have a great selection of videos and they all have worked great for me! I just run them through Image Converter and export right onto my Clie, no problem.
Also I am thinking of investing in the Sony Recorder... this will make it very easy to record TV programs and movies onto MS then play on my Clie!
oh, almost forgot.. I also load a lot of Flash cartoons onto my Clie. Go to this site if you wish:
