Depends on what you're trying to 'burn', of course... care to post further details
I'm trying to burn LP vinyls from my stereo. I was able to do this with Nero6 but when I upgraded to Nero7 was no longer able to. When I use Wave Editor I get a message "Request Runtime to terminate in an unusual way"
I'm afraid (a) you'll have to post a bit more detail about how exactly you're connecting up your stereo to your PC, and (b) that I can't offer any reliable advice on the process — I usually get my 'techie' colleagues to help out, until such time as they can deliver to me a .wav/.mp3 audio file...
I'm connecting a cable from the earphone slot on my stereo to sound card on pc. I can then listen to audio (radio, LP's etc) on my pc speakers. On Nero6 once this was working everything was OK. Not so Nero7. I emailed Nero help but no reply. I'm not too much of a whiz kid on computers.
