DesktopWeb FormText   got DirectShow working with MPEG-2 TunerTue, 14 Mar 2006 05:28:38 GMT # 

er, um ... actually i cheated. Chris Auld pointed me to MediaPortal, which is an open source media center. just so happens that its written in C# and uses a managed wrapper over DirectShow. its got a class specifically for MCE TV tuners, which is exactly what i needed. ends up i was really close, but my query for the IAMTVTuner interface kept failing, seemingly because i did not specify the FindDirection. the bad news is MediaPortal already implemented the feature(s) i was working towards building for MCE. so i could copy them (boring), implement the same feature in a different way, or come up with a diff idea ... hmm?
