Some mkv files will not FF/RW!

Hi guys,

I have some mkv files that play fine however fails to FF/RW. I tried using the instruction in here viewforum.php?f=10 and here viewtopic.php?f=10&t=3267. However none of them work.
Been trying to figure this out for the last 2 days
Any other suggestion?

Thanks for any help
