Problems with HDDVD's containing Dolby Digital Plus

[beat-breaker]

I'm having issues making MKVs from HDDVDs that are encoded with DD+ Audio.

When the Audio is Dolby True HD it's fine, the MKV works perfectly as usual
When the Audio is DD+ there is no audio in the MKV.

I've Demuxed the EVO from the HDDVD disc using EVOdemuxer then recombined and created a Bluray ISO using TSmuxer.
Then I've mounted the ISO and played the disc using MPC-HC.... The DD+ plus stream is playing and I have audio again - however it's not in sync with the video.

I've then created an MKV from this "bluray iso" and then audio is gone again!!


This happens on every HDDVD disc I own that has DD+ plus on it.

Anyone any ideas about this, a bug?

thanks

I haven't ripped any HD-DVDs in some time, but I never had that problem with DD+, DTS, or TrueHD audio based disc.
