I have uploaded the release canidate for wordTube. It contains now the swfobject 2.1 for showing the flash content and is compatible to other plugins , like Viper’s Video Quicktags. Please update to this version and report your issues at my GoogleCode project.
Please note :This version breaks the currently swfobject of NextGEN Gallery (and as well the addon’s like the Flashviewer). If you are interested, you can test also the update for NextGEN Gallery, here you get the version.
If I faced no big problems, both updates will be available end of the next week at wordpress.org
Happy testing !

Weird problem…
I am running WP 2.6.2 and after installing NextGEN Gallery my home page of my blog changes to showing latest posts instead of the custom page its supposed to display. Is there a way to fix this? If i disable NGG the problem goes away instantly!
