Im going through the process of dumping my entire DVD and HDDVD collection to tagged MP4, In order to import the audio files for transcoding to AAC i need directshow decoders.

I have tried installing ffdshow and ac3filter and opening the demuxed files in a directshow player (wmp) with no luck.

I have contacted ArcSoft & interVideo after reading that their media players support DTS & TrueHD but they were unable to confirm that their filters are suitable for this and installing the trial of ArcSoft & full version of interVideo didn't help.

Do i need to repackage these streams into a different container or something to enable reading in directshow players ?

(Ps: i know that their are software applications for this like eac3to but these are not compatible with my aac encoder card which supports directshow input)

demuxed files

This right here is your problem.

Yes. Matroska should work nicely; you will need a DirectShow Matroska splitter installed (I recommend LAV Splitter).

LAV Audio or ffdshow can decode the MLP core of TrueHD files; LAV Audio can also use dtsdecoderdll.dll from the Arcsoft TMT package to perform reference-quality decoding of DTS-HD files.

All-in-all, therefore, I recommend LAVFilters for the splitting and decoding side - and I recommend mkvmerge for muxing your HD audio to Matroska files to allow DirectShow to decode it.

Thats strange i repackaged the video + audio in ts, mkv and m2ts but only the video plays ? Im using server 2008 with the desktop experience feature installed if this makes any difference.

Have you looked at MPC-HC's filters menu during playback or rendered the file(s) with Graphedit to see which audio decoder is in use?
