I just did some research on the net and found out that an update is in the works for WMP to add the "Burn at once" feature. As far as gapless playing or recording goes I can say that the free copy of "Virtual DJ" allows for gapless and overlapping for playback and record. It's also great for simple editing example (I downloaded a copy of Johnny Burnette's "Dreamin'" and the lead in to the song was studio chit chat. I edited to the first note past the talk and it came out perfect!). You can do a lot with Virtual DJ free version but the mic is enabled with the paid version.
