You were right, it is indeed the VBI that was making these Mpeg files essentially
unseekable... I can now play them back without problem on VLC and on my PS3...

I wonder where the problem lies, in the way the VBI is embedded in the Mpeg files or
in the media players though, anybody knows?

anything else to unset...
