FM transmitter and better audio player on TF3D?

[NighthawkIX]

Just wondering, since I've the Diamond has a FM receiver, does that mean that it can also act as a FM transmitter (say for road trips?).

Also, is there a better audio player for the diamond that will work with the TF3D music tab? I like the integrated approach, but I find that the program skips a bit, doesnt support alot of formats (can't seem to get .ogg to work), and I cant push the power button to turn off the screen and get it to keep playing.
