Hi, there's some filter preference bug in Recode which should be fixed in the next update, which probably is the reason.
If you have ffdshow's raw video support enabled, disable it. If doesn't work still, check with graphedit your filter chain, and try unregistering a filter which is not Nero's.

I think this is your problem, and it should be fixed soon.
