Conflict with newly installed nero and Intervideo DVR

For some strange reason since I installed Nero on my computer my TV turner that uses Intervideo DVR does not work. I keep getting the error message window about sending the error. Anyways, as you can probably tell, I am not the best around a computer. Can anyone tell me a way to keep Nero and be able to use my Tv turner? Thanks in advance! Sorry to be bother with something that is probably really easy for most of you.
