I haven't burned any CD's in ages and it shows. I have no clue why my WMP has changed all my .wav files to .cda files and I can't get them to burn correctly. Nice that they are smaller but I am reading that .cda is a windows feature only? Is this right? Will we ever be able to use them with other things besides WMP. (probably doubtful)? Oh well, I only have WMP 9, I hate 10 and 11. They have way too much junk in them and I don't want that on my computer but if windows is going to put files like .cda's as being the only way I can use WMP, then I may have to change players, or, have they all gone to some off the wall different file too.
