Have you ever opened mplayer fed by a PVR-250 in one term window, and
changed channels in another? The channel changes are almost
instantaneous, whereas changing channels within Myth takes on my system
about 4 seconds.
I don't care about whether live TV records or not. Whatever the devs
want to do there is fine. But channel change speed *is* broken, no
matter what anyone else says. There is no reason why it should take 4
seconds (or for others, even more) on a PVR card. Maybe for Firewire or
other input sources, I'm not sure, but not a PVR-x50. Sure, you need to
buffer a bit to disk, that's cool. Maybe ten frames (about 1/3 of a
second) should be plenty, not 3 seconds worth.
