Hi all

I get an increasing problem with die know mkv file bug (ticked 336 + 331 - to me it seems to be the same problem). I don’t need to transform the files to ts but it seems that this bug makes the files unplayable for my wd box. I didn’t had this problem with the 2.11 release. So as there seems to be no workaround or cleaning process for these files available, I would like to go back to 2.11. Is there an easy way to do this under Umbuntu 10.04.
Or is there any other tip?

Cheers

Janko
