Sound dropout on MKV / BluRay

I’m having a problem of sound dropout when playing BluRay MKV files.  Everything works find for about 5 or 10 minutes and the sound drops out.  I hit stop, rewind a few frames and play and everything is fine for about 5 to 10 minutes and then the same thing happens again.  I converted the files with DVD FAB BluRay Copy.  Below is a Mediainfo on the file.

I have a first generation WD player with the latest firmware update.  Files are stored on  a WD 1trig Passport HD.

That’s an extremely high bitrate for an MKV file…   That’s my guess…

I think you’re right, Tony – and he doesn’t even have a Live, so the buffer is probably even smaller with that first gen player.

I suspect the Live would handle that file.

What can I do to correct this problem?

Run it through Handbrake’s high profile preset.

But do change the output type to MKV (and pass through the AC3/DTS sound track you want).
