I don't EVER expect MC to be able to burn CDs. Why? Because very few people want to do that any more and the population is getting smaller. The feature presumably requires some engineering time on JRIver's part and they don't want to spend the time/money doing this for such a small return.
Of course I could be TOTALLY wrong on this. I don't work for JRiver, nor do I represent them in any way.
On the other hand, the program I use to rip CDs does really nice CD burning also: XLD
I've ripped hundreds and hundreds of CDs with it, and I only discovered that it could burn CDs a few weeks ago! It's actually very convenient because it has a feature called "open folder as disc". You just point it to the folder that contains the album you want to burn, and that's pretty much it. Select your burn speed, insert a blank CD, and press the Burn button.
