I have a problem with the Media Server. When authentication is enabled, the client is unable to play WMA files, giving an "unable to acquire license, error code 0x80070005" message. The files do not have DRM enabled. MP3 files play fine. WMA files play fine when authentication is turned off.
I've noticed that a few other people reported this (or a similar) problem. I understand that this may be due to an interaction between MJ and WMP9, but I don't consider uninstalling WMP9 or re-acquiring all my media in a different format to be viable options.
Considering that MJ8 is no longer actively developed, I would like to request an official statement from the MJ team: will you (try to) fix this bug in MJ8? Is it fixed in MC9?
If you want to fix the bug, I'd be happy to help you isolate it. As a possible lead, the Media Server shows the following messages when a file fails to play:
unknown header <X-Accept-Authentication>
unknown header <Supported>
Software versions involved:
MJ 8.0.400 (registered)
Media Server 1.0.135 (protocol v0.9)
WMP 9.00.00.3075
WinXP/Pro, all patches
