 	Not intrinsically, but practically, yes.  The streams produced by 
ivtv aren't necessarily *broken*, they're just a little more complicated 
than most linux tools expect.  If you're not trying to cut out 
commercials, you might be able to remux (using replex or dvb-mplex) 
*without* demuxing/remuxing.  In that case, you just insert the VOBU 
streams (required for DVD authoring) as it goes without having to 
demux/remux.  I have had some streams where these tools get confused 
anyway, though.

 	Most of the time, transforming to DVD assumes that you want to 
remove the commercials, I'd think.

 	True, but it's not just an issue with mythtv.  There are a couple 
of frontends (mythtvburn looks pretty sexy, for instance).  The trouble is 
that the backend tools don't exist in non-broken form.  The mythtv devels 
are busy working on the stuff they want to, which tends to be PVR-related 
stuff... not mpeg crunching utilities.  Those should rightly be reserved 
for some backend engine... it just happens to not exist completely yet...
