look at the upload rules...one of your vids (something with piano) had this girls-boarding-school at the bottom all time...maybe theres a problem with copyright i think...
uploading is easy just name your file example
E.mpg or whatever avi mp4 wmv then put on your computer like this C:/E.mpg if you want to upload divx change the extension to mpg or avi ect.. xhamster will post it anyway. all my videos are divx a good free 30days anyway program is the divx converter and divx author 1.5
author lets you cut and edit and compress and its free for 30 days Mine just ran out just might have to buy it.
