My sat.reciever has <b>much </b>quicker channel changes than MythTV and
it has PVR abilities and is Linux based. It's a Dreambox.<br><br>
Is really "tune the channel" an issue at all? Doesn't the tuner
do that almost instantly?<br><br>
I love Myth but I really do think that channel changing times are tooo
long.<br><br>

There was a recent lengthy (and somewhat heated) thread in the dev
list<br>
about this. The technical reason for the delay is because the
system<br>
has to do the following things when changing a channel on "Live
TV":<br><br>
1) Tune the channel.<br>
2) Start encoding the feed.<br>
3) Store the file.<br>
4) Decode the file.<br><br>
Each of these steps takes a little time. If you don't do them, you
lost<br>
the ability to pause or rewind Live TV, which is one of the sexy
things<br>
about a PVR.<br><br>
I don't really understand most of what goes on in the developer
list,<br>
but that has been some effort to improve tuning (mainly for DVB
cards)<br>
and store Live TV more efficiently, perhaps doing away with the<br>
ringbuffer entirely. So things might get a little better around
the<br>
edges, but there's always going to be some sort of delay (and you'd
get<br>
this delay if you had a satellite, digital cable, or Tivo as well)<br>
