Play-To feature stopped working

Hiya all,
There is some background with this problem here. That did solve the problem then, but any subsequent tries still don't work. it works on some videos, not on all (which are basically the ones which are important)

I read up somewhere on google that it might be due to the VM I have installed [as XP], done a little wildcard tinkering by disabling Virtual PC network Filter driver with no luck (testing done by closing and reopening WMP). I'm at a loss now of what to do.

Sorry if this is in the wrong sub forum

Reinstall WMP.
