Where can i find the changlog of nero recode2.5.5.0?

@Wishbringer: Make sure one more time that you indeed have the latest Nero release installed. There was a similar problem with nevideo.ax filter earlier, but it should be fixed in Nero 7.10.1.0.

Did a Deinstallation, rebooted and still found some *.ax filters in "Common Files". Deleted them by hand, reboot, new installation of Nero 7.10.1.0 again and... I can play my own clips without problems! Thanks JohnV for the hint. I found out, that nevideo.ax was an old one, but was overseen by old deinstaller and not overwritten by new one.
