0Haali Matroska logoProblems with DS splitters playing a range of m2ts files

Ever since settings up a HTPC running Win7 Media Center I have had the occasional problem playing m2ts files. ffdshow supports all of the codecs used in m2ts files but still a few files play without without either audio or video, or the playback isn’t smooth despite more than ample hardware. I have experimented extensively with both haali matroska splitter and gabests mpeg splitter but both have their flaws.


haali doesn’t seem to correctly support HD audio formats, and whilst gabest does it has problems with some of my files – particularly those that are 1440×1080 rather than 1920×1080. Eventually I discovered the following simple work-around.
  1. Install both gabest and haali splitters (enabling mpeg-ts in haali).
  2. In the registry browse to [HKEY_CLASSES_ROOTMedia TypeExtensions]
  3. Make sure there is an entry for .m2ts and add an entry for .m2t
  4. Inside each there should be a string named “Source Filter”
  5. Set the source filter for each of the 2 files to the CLSIDs (see below) of each of the splitters (e.g. set m2t to haali and m2ts to gabest).
  6. Change the file extension of any .m2ts files that are problematic to .m2t. They will then play via the other splitter – which hopefully won’t have any problems with them!

Gabest CLSID = {1365BE7A-C86A-473C-9A41-C0A6E82C9FA3}
Haali CLSID = {55DA30FC-F16B-49FC-BAA5-AE59FC65F82D}

Please note – the above refers entirely to x64 codecs, splitters and players. It should work the same for x86 32bit but I haven’t tested it

—update

I am now using .m2ts and .ts to discriminate as the .m2t extension isn’t recognised by Media Center Master.  .ts and .m2ts are also supposed to be interchangeable – they both represent an mpeg-2 transport stream.
