video to mp3 converter apps

First I had Tube Downloader and then one day it wouldn't work. So I go to do a re-install and it's gone from the market. But it was cool b/c I now had YouTube VideoBox. I used it a couple of times a few weeks back and everything worked great; I had no problem converting videos to mp3. Tried it today and it only downloads videos; no converting options at all. I looked in the market for a replacement and nothing.

Is there some reason that I can't convert? I upgraded to 2.1 but it's strange that VideoBox is still here, but I just can't convert. Are there any apps that does the conversion?
