This is largely a MythTV problem. If you're using mplayer and
ptune.pl, you'll see that changing frequencies is actually pretty quick
(although sometimes my mplayer slowly gets behind making it seem to take
longer the longer I watch). Myth runs a few seconds behind always, plus
does a lot of extra work to switch channels like pausing and resetting.
Even with a version that I've hacked which just does a frequency
control, I'm still looking at 2+ seconds per channel due to the
prebuffer. I'm looking at ways to eliminate that as well.
This is true, but some of it is driver related. There are some new
module options in 0.3.6r for buffers that seems to fix this a bit.
There was a bit of discussion about the options, I think mpg_buffers=8
helped.
Yes, I can confirm this (Brett Bieber reported it initially). With my
PVR-500, specifying mpg_buffers=8 cut my channel change time in half (from
about 4 seconds to about 2 seconds). Haven't tried increasing it any more yet!
