Yeah, 44.1kHz, 16 bits, stereo, is the unchangeable requirement for CD Audio - though I thought that Nero would convert from other formats if necessary.
An alternative approach is to use ReaBurn and its associated programs (the key one is Burrrn) - see
http://www.inside-audio.nl/joomla/do...er_addons.html for the download, which offers a variety of features to make burning CDs from Reaper renders quick and easy.
I see from the hit counter there that 465 people have now downloaded it - cool!
