Well if the visitor had a computer that would play mpegs it would  
work out. At least they would have the information and could perhaps  
make their own "consumer" disk.

This is not a fully-formed concept, just a thought that may well have  
mutually-exclusive ideas in it.

Some capture devices can encode "DVD compliant" video, whatever that  
means. I know the Plextor can do it, but that functionality is not at  
present supported by Myth, though you'd still have to mux the audio  
in. Certain commercial PVR software can write "DVD compliant files"  
pretty much in real time.

I think the mpeg-2 coming off a PVR card does require some  
processing, which is why MythBurn takes significantly longer than  
just writing the data.

Even if you had to do some significant processing, like split and re- 
mux, with CPUs getting faster and faster it should be possible, if  
not today then next week.

Anyway this is the way the process works: Somebody comes up with an  
idea, several hundred people explain why it can't be done, then  
somebody does it :-)

Thanks for the feedback.
