Wine 1.5.6 console output

SlingPlayer 1.5 fails to show video if Wine is upgraded. Sound works fine.

I have tested this over and over and it is the act of upgrading Wine that
appears to be causing the problem.

Native quartz, qcap and gdiplus needed to get this far.

Tested:
1.4.1 --> 1.5.6
1.5.6 --> 1.5.12
1.5.12 --> wine-1.5.12-157-gbdf9a9f

Following the upgrade there is some new output in the console:
err:ddraw:ddraw7_QueryInterface
(0x1ee6f8)->({aca12120-3356-11d1-8fcf-00c04fc29b4e}, 0x16d554): No interface
found

And this line disappears:
err:ole:CoGetClassObject class {7d8aa343-6e63-4663-be90-6b80f66540a3} not
registered

7d8aa343-6e63-4663-be90-6b80f66540a3 is related to quartz.dll
(http://mikolajapp.appspot.com/uuid/query?q=%7B7d8aa343-6e63-4663-be90-6b80f6...)
and this somehow becomes registered during the transition, and stops video from
being shown in the SlingPlayer.

I cannot understand what would cause this.

Attempting to unregister fails:
Failed to unregister DLL c:\windows\system32\quartz.dll

No known workaround: I have to reinstall SlingPlayer every time, or lock the
upgrades on my system.
