As 1.6 uses .NET 4 at least a recompile is necessary to get it running. But as long as no sources are available, cul8er is the only one who can do this.
You could try this UNOFFICIAL FH from our dev Sebastiii - recompiled for 1.6.
Copy the dll into your %MediaPortal Base%\plugins\process folder (MAKE A BACKUP BEFORE!)
Use on own risk - No guarantees at all!
