Hey Steven... thanks for the advice. Did you happen to install nero after premiere pro, etc... or was it on the system before? From what I read, a lot of the conflict arises from installing this stuff after Adobe software is installed. Because of the registry priorities.
Take my advice and AVOID Nero 7.0. It is the root of all problems on my systems. I used to swear by it, now I swear at it :)
Seriously, it has become massive bloatware. If you want a simple data burning program, have a Google search for Sateira Software, or UltraISO or Easy CD-DA Extractor - all SIMPLE data burning programs that I have found useful. There are many others (shareware) that won't bog your system down with unneeded video & audio codecs / program applets you don't need.
