Some people are having issues getting WMV9 in TCPMP working with WM6, particularly those of us who are trying to use TCPMP with Orb and are getting a nasty WMV9/WMA9 not supported error. This is because WM6 includes newer versions of the WMV and WMA codecs, which are named differently than WM5's codecs. Orb does work with WMP Mobile 10 and Conduits Pocket Player, but the video is incredibly jerky for some reason which I haven't been able to nail down yet, and I doubt I'll look into the matter anymore now that this works.
The fix is simple...just drag the old WM5 codecs into your Windows/ directory and reinstall TCPMP. After that, you should be able to use TCPMP to watch your orb stream (Windows asx stream on Orb 2.0).
I've included the codecs here in this post. This fix was tested using the Most Beautiful ROM. Let me know if it works for the other ROMs.
