Video upload question

[SJC Alien]

Hi to all.
I am using the new jetvideo page to upload video's I did have one upload A-Ok, It is at KSJC. I also loaded 4 other video's - all of those 4 were rejected as the reason - (failed to upload.) I did everything the same - no different. Does anybody have any reason or clues, as why one video was uploaded A-ok, but the other 4 didn't - as far as I know - I did the same routine for all of them - I make them on Windows Movie maker - save them all the same- and upload with the correct data.

Thanks
Tom
