After attempting to install a dual channel Hauppauge card into the General, with the associated software installs/deinstalls – Windows Media Center could no longer see any TV Tuner Cards. This had been bugging me all week.
As always, I am determined not to go the de-install/re-install of Windows solution to problems. I’d much prefer to logically think through the problem, and learn along the way.
I found that the ehRecvr service was failing to start with a “file not found†error (check in the logs in
C:Users<username>AppDataLocalTemp) … and further checking showed ehRecvr was attempting to read a value from the registry:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionMedia Center
Comparing this branch of the registry with a known-good version, I found that something had lopped significant sub-branches off such as “…Start Menu…†– in fact, only 3 branches existed in my registry.
I suspect that one of the de-installs in the swapping from Hauppauge to/from DVico caused this, and a quick export/reimport and all is well. Subsequently, components of the Windows Media Center software were set into a strange half-state of working.
Hope this helps someone.
