We mentioned Vectir a bit back as a very powerful remote control app for your PC. It allows you to control your media players like VLC, Winamp, iTunes, and more from your BlackBerry smartphone with ease. They have a client that works over Bluetooth and another that works over Wi-Fi so you are covered both ways. You can also add your own custom remote macros for other apps which is a big perk.
The Vectir app has a nice 30 day trial after which you can pick up a copy of the app for $14.95. (currently $4.95 in a limited sale). It works with quite a few devices and the app just got a nice update for both variants this month.
Check out the solution at www.vectir.com or find the Bluetooth variant or Wi-Fi variant in App World
