As Cyrius said on IRC (yes, I'm a lurker) there's no use for a seek table or cue
entry if it's split in many parts throughout the file. If it is spread among the
file, it should always be the same one (reemission during a stream for example).
For the VDub case, I think the placeholder I just talked about should be enough.
Note that the Cue entries can still be at the end (should be much bigger than
the Meta Seek entry) and contain the position inside the Meta Seek entry. (cue
only define the position of a Cluster+Block according to a timecode, the Meta
Seek entries can be specified for any matroska element).
