This does not have to do with double layer, but simply the timestamps in 
the mpeg stream. even a 5 minute movie you can reset the timestamp ever 
ten seconds if you want.

Finding out the correct length of the MPEG video and the current 
timestamp/filepos correlation is not doable without first scanning the 
entire file (or using some obscure helping mechanisms -> summing up the 
chapter run length, or what ever else...)

Half (or more) a year ago there was already a discussion here about this 
issue.

Subtitlewise one could help by implementing a display on frame count 
which would not reset, but would be out of order if one starts to seek :(
