ukulele_ninja,

As an Entertainer developer, I appreciate Gargamella's kind words, but of the three main features that you're looking for, Entertainer only really supports the third one (IMO). But, Gargamella is correct in that it is a project that is still under heavy development and is relatively young compared to other media center projects.

If you're interested in playing around with it, I would suggest looking at
