I mean I don't want to limited myself here but my plans are more so the first choice than the second. Can't I install both or bad idea? Also your link above says AMD64, I am running on a Intel Dual Core... Does that matter? ...and just to make sure, I want only these two? Here's the path for FFDShow x64 and Matroska x64 http://sourceforge.net/project/showfiles.p...lease_id=523000 When you install FFDshow, in the audio section, don't forget to tick SPDIF for AC3 and DTS, this way your Dolby Digital signal will passthrough to your Receiver without been decoded by FFDshow http://downloads.sourceforge.net/guliverkl...mp;big_mirror=0
