I use Fedora 12. I created the video and I can play the video fine. While I understand your point, it's not fair. Would it have been better for me to not produce the video at all?

Thanks for the bug link. I did the former. I didn't have the time to do the latter. I was hoping to get the upload to blip.tv working as blip.tv can do the transcoding server-side.

But a trivial test case should be able to reproduce the issue. ~m -- Fedora-marketing-list mailing list Fedora-marketing-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-marketing-list
