APE files are monkey's audio file format. Sorry I don't about a CD Burning application that burns APE files directly to CD Audio. But there are converters which could convert APE files to a more compatible audio format. Try Easy CD-DA Extractor. It supports converting APE files to MP3, WMA etc. And then you can burn them to CD Audio. Perhaps, it supports burning directly to CD Audio.
I uninstalled it as soon as I finished experimenting with Ogg Vorbis.
Since you have encoded them to a lossless audio format, it is not a good idea to convert it to a lossy format. Try to convert it to WMA Lossless, if only Easy CD-DA Extractor supports burning WMA to CD Audio. If not, then convert to MP3 320kbps and then use an app like Nero Burning ROM.
