I have been struggling for a while to make WHS 2011 to stream WTV files over the web access interface (which uses Silverlight). I have been using Shark007 in WHS 2011 and it works locally for all formats: WTV, MKV, MP4. However, when using WHS remote web access only MKV and MP4 work. I mmade some searchs and looks like current Silverlight version in WHS 2011 does not support AC3 (Dolby). I am not an expert on DVRMSToolbox so It would take me ages to create a profile to make it work. The WTV files are created using Hauppage HD DVR so I suspect there is a lot more people having the same issue. Any help or direction would be appreciated.
