M4V files and PS3

[cutthroat]

So I have a few MKV (M4V) files I ripped with Handbrake. When I try to play these back on my PS3 the audio is good, but the video plays really fast, like the fast forward key has been pressed. Any ideas?
Thanks

Are you using the latest released Mezzmo v2.3.1? If you are, would it be possible for you to send us one of those files (through a site like www.megaupload.com) so that we could try it here?
