I tried both uninstalled and a clean install of xiph-qt-20090529.dmg
and all the files I encoded are playable in QuickTime player. Does the
error appear for all the encoded files? What about oggs not produced
by OSX/QuickTime tools?

The "error -50" sounds pretty general, I suspect there could be
something wrong with the installation. Can you try doing a clean
install (remove any old components + install xiph-qt-20090529 +
reboot)? Do you have other 3rd party QuickTime components installed?

Following suggestions, I guess I should make 3 sets of binaries for the release:
 - built with the latest stable releases of the Xiph libs (would be
the default download option),
 - built with HEADs of the trunks of the libs (what I used to do),
 - built with HEADs + Thusnelda

I think that could work with changes to the download page so it's more
obvious what to download if one's not sure, and less cluttered.

Thanks a lot for helping testing!
