TsReader.ax FFDShow video decoder AV sync workaround fails when 'Core CC Parser' filter is used, because TsReader.ax assumes decode filter is directly connected to it's output pin.

h4. Steps to Reproduce
See http://forum.team-mediaportal.com/threads/tv-lipsync-problem-when-using-ffdshow-on-mp-1-3-0-beta.115071/

h4. Additional Information
Current fix is to add registry setting to TsReader.ax, so that FFDShow sync fix can be forced 'on' by the user if required.
