Audio Sync issue

[ignite]

Hi All

First posting to this forum so apologies if this has been covered already, but I did try a search and couldn't find any threads specifically addressing this.

When I rip my blu-rays with the exception of one title I allways seem to get audio sync drifting towards the middle of the film. This then stays out of sync there after.

I'm playing these MKV files on a gen 1 WDTV, it could be perhaps it's this unit that is causing the issues.

My DVD rips are just fine however.

Any advice greatfully received.

Thanks.

What is the disc title? If you run file through mkvmerge, will the problem go away?

hi, it was the harry potter number 7 the deathly hallows part 1. By the end of the film it's like watching a badly dubbed "adult" film!

Unfortunately I'm on a mac so the software you mentioned isn't available to me, i'm being walked through how to run this stuff on my mac tho!

I suspect it won't help tho as if it's the seamless branching thats the issue with the delay will vary with every "branch"?

I sort of hoped in the mean time I could just make a backup of my blu rays and play them as std disks, but I cant find a player that would allow me to do this.

Mkvtoolnix doesn't work in OS X anymore?
