It builds fine here, make sure you use gmake.

02, 03, and 04 all have the same tuning parameters and use the same
audio and video pids, only the pmt differs. It seems that these are
regional channels that were broadcasting the same program at the time
you were scanning. Try scanning again at different time to see if you
get different pids.

tvtv has both the audio and the video pid set to zero so it probably
contains some other than video or audio data. Typhony can only handle
audio and video data.

No its' not. Does it happen only when you are switching from one channel
to another channel, or also when you are tuning to a channel from the
stopped state? Also is it printed once after a channel switch or every
second?

Either you are using an old version of the driver or you have build
the driver with diagnostic on, I suggest you don't build the driver
with diagnostic to keep your dmesg from getting spammed.
