My mistake... when dealing with MJPEG the "0" in current0 has meaning (it is the camera number that you want a stream from). In WMV-land it is meaningless.
When you set up WMV Streaming in Config you need to use a different Port for each camera. Then in Media Player you choose the camera by choosing the port.
Example:
Cam 0 is configured to use Port 9090 for WMV Streaming.
Cam 1 is configured to use Port 9190 for WMV Streaming.
Cam 2 is configured to use Port 9290 for WMV Streaming.
Cam 3 is configured to use Port 9390 for WMV Streaming.
URL for Cam 0 is mms://192.168.1.100:9090/current.wmv
URL for Cam 1 is mms://192.168.1.100:9190/current.wmv
URL for Cam 2 is mms://192.168.1.100:9290/current.wmv
URL for Cam 3 is mms://192.168.1.100:9390/current.wmv
Audio: It looks like the WMV 9 profiles that come with AbelCam are mostly no-audio profiles. Here is a file that will be useful:
http://eeberfest.net/AbelCam/profile.zip
The zipfile contains:
TyXmas.prx - a WMV 9 profile I made that includes audio. Put it in C:\Program Files\AbelCam\data\profiles. Re-start AbelCam. Go into your cam's WMV Streaming config. Make sure WMV Version is set to 9. Then choose TyXmas as your Profile File.
WMProEdit.exe - Microsoft's own WMV Profile Editor. Lets you modify and save .prx profile files.
ProfEdit.chm - help file for the profile editor. Put it in the same directory you put WMProEdit.exe in and it should be found when you hit Help from within the editor.
