Unless I'm missing something - PTS is the only thing you should be 
worrying about for seeking. DTS will be out of order for frames when 
you're seeking...

i.e. if you're seeking +1 second, you're intyerested in decoding the 
frame at +1 second. This may mean you have to decode frames either side 
of it, but this has nothing to do with decodinga  frame that needs to be 
decoded at +1 second...
