RingBuffer.cpp
There are a few places where it waits for a full 256K before doing
anything. 30 frames may take as little as 100K so this can account
for about 2-3 seconds. And some of the timeouts on waiting for the
buffer to fill are LONG, and there is no mechanism for flushing to
disk based on time rather than buffer fill... You might also want to
start live TV at 90% of real speed and speed up to 100% when the
excess buffer has grown to at least 2-3 MB ahead.
I think also there is a lot of sync stuff waiting for playback to pause
and audio to pause, etc, etc. I have tried a few patchsets on this in
the past and also reduced the buffering and you can drop the wait times
by a couple of secs easily. I haven't submitted anything because I
don't really understand it all that well so it's a bit of a hack
I hope someone who understands this better will do some optimisation
because it's currently really wasting a lot of unneccesary time.
Finger crossed...

P.S. I can't see any reason to sync on the audio pausing...
