I only burned a CD from inside Reaper one time but it worked OK... If I recall and what Justin is saying also, is that there needs to be markers to define the start and end of each track on the CD... so at least a start and end [if I recall]... When I did it reaper was in an older ver. and I think the CD makers had to begin with the # symbol or the !... don't remember but it is in the user guide... I think I was told that in newer versions those symbols we no longer required, but the markers are still required... Sorry for vageness, but I use other burning tools now
