Sorry for the delay (been on me hols), I'm not on mythtv-vid but I'll
give it a go...
may take some time....
BTW, I think that theoretically there are some circumstances where bob
deint would be the best way to go.... for instance when you get a 16:9
signal (i.e. most DVB-T it seems) and display it correctly on a
4:3.... because of the scaling you can't line up the fields correctly,
so theoretically the display may output lines out of field sequence.
Bob, by being dumb avoids this problem by only showing one field at a
time. (of course there are other problems then...)
How does your soln cope with a scaled picture like this?
