[QUOTE="DiskHead, post: 728791, member: 112323"] I figured out the problem.. at least for me, as to why the Ceton tuners don't show up. It's because I am running a 64bit operating system. TvService is set specifically to x86 only, while TestApp is set to AnyCPU. I confirmed this using GraphStudio: 1.) Download the 32bit and the 64bit version of graphstudio here: [url=http://blog.monogram.sk/janos/2009/06/14/monogram-graphstudio-0320/]RadScorpion’s blog » Blog Archive » MONOGRAM GraphStudio 0.3.2.0[/url] 2.) Perform these steps, posted by MM earlier, first with 64bit graphstudio (the BDA Sources exist) and then with 32bit graphstudio (the BDA sources do not exist). 1. Download GraphStudio from here. 2. Run GraphStudio as administrator. 3. Click "graph" -> "insert filter...". 4. Select "BDA source filters" in the drop-down box in the top left corner and "all filters" in the field beside it. I was thinking 64bit users could use CorFlags.exe to change the headers of all the assemblies to allow 64bit but will that break MedialPortal? I assume MediaPortal was forced x86 for a reason? Some investigation into building MedialPortal TVService as 64bit revealed a ton of DllImports of 32 bit libraries which won't work without alot of work. I think I will just install the tuner card in an older dual core system that already has Win 7 32bit. [/QUOTE]
