'this movie could not be played' error

[pete100]

I have a jailbroken iphone that was showing Youtube/videos just fine when suddenly today i see this error: this movie could not be played.
Prior to it I just synced and uploaded a new video file i bought from hotfix.com
Any ideas what the problem is and how to solve it.

I cannot see anyone else with tshi issue - bar the problem aon 30th Oct with youtube not working.
