Sorry to hijack this thread but I need help.
* What didn't work
Everything... I use SetPoint 4.8 with a Logitech Media Keyboard Elite.
* Whether the media keys work in foobar when it's focused
Nothing. SetPoint didn't recognise Foobar 0.9.6.9 so... no keys are working.
* Your version of Windows
Windows Vista Home Premium SP2. I would also add Windows 7 RC on Dual-boot.
* Your version of Foobar
Like I said above... 0.9.6.9
* What keyboard you're using
*sigh* Logitech Media Keyboard Elite.
* What drivers / software you have installed for your keyboard
Logitech's... aka SetPoint
* Anything else you think might be relevant
Yeah. I've also set foobar as my CDA player but pushing the Media Button on my keyboard opes iTunes instead of foobar2000. (Btw, iTunes is there only to buy music... nothing else).
Foobar doesn't recognize the Play/pause button... neither the Play one... etc.
Thanks for your help.
similiar setup to mine, so here is what i did:
1. configurate your keyboard shortcuts in foobar2000, don't forget to check "global shortcut"
2. move to your setpoint directory (for example: C:\Program Files\Logitech\SetPoint)
3. open the file "players.ini"
4. add one of the following lines to the [players] section:
- if you use the default interface in foobar, add this line:
foobar2000=wac,foobar2000.exe,{97E27FAA-C0B3-4b8e-A693-ED7881E99FC1},xxx,xxx,xxx,xxx,xxx,xxx,xxx,0,1,foobar2000
- if you use Columns UI, add this line:
foobar2000=wac,foobar2000.exe,{E7076D1C-A7BF-4f39-B771-BCBE88F2A2A8},xxx,xxx,xxx,xxx,xxx,xxx,xxx,0,1,foobar2000
5. save the file 
6. restart setpoint (exit, start)
7. should work now
