I think peter meant it would be cool if "Add Audio CD x:/" was in the ADD Button menu in the Playlist Editor. Currently you can only add file/dir/url, whereas the only way to play an enhanced CD is to use main menu -> Play Audio CD x:/
This is why topics like this should be posted in the Wishlist Forum, because it is a request for a feature and NOT a bug.
He also meant that you should save your current playlist first, then goto "Play Audio CD x:/", remove the unwanted trax from the playlist, then go back to Add button and add your saved playlist. Naturally, you may also need to drag the new cda files toward the bottom of the list first, then resave the playlist.
Yeah, sure, this is a bit of a pain, but only takes a matter of seconds to achieve, regardless of how lazy you/we might be
Besides, why would anyone want to add Audio CD trax to their main playlist when you can only play them if the actual CD is in the drive. You don't have multiple CD-ROM drives (like more than 10 or something) hooked upto your system by any chance do ya?
What I do is to enable multiple instances, keep the main playlist intact in the first instance in the background, open a new instance to play extra trax/Audio CD's, close the new instance when done, thus leaving the original instance still open with the original playlist. Piece of cake
