Thats funny, cause nero 6.6.0.6 to 6.6.0.8 changelog claimed it added dvd -dl and litescibe, infact most looks the same, i bet its a bug fixer, hense only letter "a" added not new build.

Does Anyone has any valid license keys for new video codecs, namely VP7 (www.on2.com) and HDX4 (www.hdx4.com)?

I have just checked the nero.exe file of this installation file and here is what it says: Nero Burning Rom 6.6.0.8g [www.home.no]. Maybe they have silently updated it from a to g.
