Video upload weirdness

I have been trying to upload the screencast I did for Pageflakes onto and YouTube so it’s a bit easier for people to access. Trouble is, I’m not having much luck with it.

My screencasting package, BBFlashback, has produced a 60-odd mb WMV file (am back on the Windows machine for this job, folks) and everytime I try to upload it to a video sharing service, the resultant video doesn’t move – my dulcet tones work their way through producing a public Pageflake page, but the screen just shows the original image from the start of the clip. Then, when the audio stops, the video starts moving.

Is there something I am doing wrong here, chaps?
