there needs to be an element of time involved though... just keep on

When zapping through I do not want the extra load for setting up a new
ringbuffer.
If this are milliseconds, I agree with you.

I never use LiveTV because changing channels are to slow.
I suggest to have an option for 'fast-changing-channels' where the input is
immediately directed to the output for the specific amount of time (say 1
minute).
This allows fast changing channels.
After this time the normal LiveTV behaviour starts, but we still keep
receiving the currently received input data.
The first time we halt or rewind to move over to the ringbuffer behaviour.
About the option when provided in seconds: 0 = normal LiveTV behaviour, >0 =
seconds to start LiveTV behaviour.
Just an idea. When implemented I will use LiveTV.

there needs to be an element of time involved though... just keep on
displaying realtime data until there's a reason not to. Hit pause and
there's a bit of lag while the display transitions from raw capture to
decoded ringbuffer. From then-on, it's ringbuffer until you change
channel.
Interesting to hear that the ivtv drivers allow for simultaneous
raw and encoded data. I wasn't sure if the hardware could transfer both
at the same time over the PCI bus. The potential issue with this solution
would be the increase in PCI bus traffic. If two or three bttv-based
cards can already exist in one system, though, this would be easier than
that.
