Understood. But it's poor sales for fedora when you use an approach
which works less well for Fedora than it does for windows.
Obviously excluding non-linux users is not an option.
I don't use Windows. 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? Because that's
how I'm feeling now.

CELT? Celt is completely inapplicable for this use case. PiTiVi
shouldn't be offering it.
And I understand that completely. I was trying every free option
available in an attempt to produce a video with clean codecs.
This bug sounds vaguely like what you experienced:
https://bugzilla.gnome.org/show_bug.cgi?id=600215
One possible work around would be to render to high quality MJPEG in AVI
(which is effectively lossless) plus PCM audio then use a tool like ffmpeg
to Theora to transcode.
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.
If you'd like to transcode it for me, that would be really helpful.

There must be a bug, because the encoders alone are no less speedy than
what you ended up using, at least not in any material way.
I've never used pitivi before, but I'll install it and attempt to reproduce
your issue. Could you possibly make your project file available to me if
I'm unable to reproduce this with a trivial test case?
The project is 64 GB.... I can't think of any reasonable way to share
that. But a trivial test case should be able to reproduce the issue.
