Well I can't tell what the reg settings are that the update made for A2DP since it restored my manual settings over the top of them. =/
If someone that hasn't installed my A2DP cab could check the registry under
HKLM Software\Microsoft\Bluetooth\A2DP\Settings and report what the values are that would be cool.
Edit: Nevermind, I just hard reset to get the values. And what were they? There were no special settings. It just uses the defaults and the defaults seem to be just fine. Vzw did a good job. Seems to take up less cpu resources now also.
