So I'm trying to sync The Terminator PCM Mono track to the US Remastered BD.

I've tried adding a delay in MKVMerge, and this works well in VLC.  However when I play on my hardware media player, the video goes black after a while and then the device crashes.  I'm thinking it doesn't handle the audio delay flag very well.

Now I want to take the WAV file and cut the unwanted section from it without losing any quality.

The format from VLC reads:

PCM S24 LE (araw)
Stereo
48000 Hz
24 bits per sample

How would I best achieve this?
