Well, it's probably doing what you told it to do :). Remember, the FF  
stream is 1/12th of the normal mode stream. So if you pause and then  
issue the play with scale value 12 for the FF stream, and use the npt  
start from the same time you paused at in the normal stream, you're  
start point in the FF stream with well off (by a factor of 12).
You'd need to basically use the pause time and divide it by 12 to  
start the FF stream at the approximate location of your normal  
stream. Or at least that's my guesstimate of what I've ahead of me  
once I get the stream decoded. Fun indeed.

The problem I have is to do with the decoding of the MPEG stream.  
It's a different stream so I need to flush something to get it to re- 
setup the stream params. What that is I don't know yet. I'd hoped  
setting the i_pcr and i_pcr_start to 0 would be what I need, but  
obviously not.

Thanks for the repsonse though, your the first bite I've had :)
