Hello There
I use a similar set up, i.e i have a mac mini connected to my BV8- 40, Beoport, BC 2 and beolab 9's.
I wasnt overly impressed with the quality of sound of mp3's so have connected all through a DAC (Cambridge Audio).
This has improved the sound enormously.
I can use the beo 4 remote to turn on net radio and net music. Dont stream videos so much, but the tv doubles as a monitor so can pull up any web sources. Ive connected a wireless keyboard and mouse for full functionality.
Of course with the recent updates to itunes, beoport software isnt fully compatible- ie you cant scroll through all the playlists using the beo 4 remote. Earlier than 8.0 you can.
Hope this helps
David
