Acctualy, i don't think it would be that hard. The only problem is that 
certain DVD nav packets, that need's to be embedded into the MPEGII 
stream, normaly contain forward references into the stream.

The creation of those packets would have to be defered long enough to 
know those references. I'm not sure how long this would normaly be and 
how much memory that would need. My guess is that we might have to 
buffer 2 to 5min worth of data in memory, before we know those values.

An alternative solution would be, to embedded incomplete nav packets at 
record time and fix them up after the recording has been finisched. This 
would mean, that you have to store the recording on harddisk first and 
that you *could not* record in real time to DVD-R's.

Any thoughts?
