Looks like png2theora disappeared in later F8 releases; was this intentional? I'd hoped to use it from a script I'm packaging (although it wasn't working particularly well for me yet, I still have hope...) Thanks!
Not intentional. 1.0beta2-2, which fixes this has been tagged for inclusion into the F-8 release (because it also fixes another graver bug), and should show up in the next rawhide push.
