May work for you, if you still have problems.  It shouldn't be necessary
to do this, but for some reason the beta cx18 driver with the HVR-1600
(74041) can be non-responsive for short intervals quite often. 


I also tried checking to see if it was a tuner input problem by playing
a DVD into the Composite 1/Audio 1 port of the HVR-1600.  The behavior
is essentially the same whether using the NTSC tuner with a strong
signal or the Composite 1/Audio 1 input.  So I won't blame the tuner
yet.  (I was really hoping for a tuner problem, those are easier to fix
IMO.)

Yup, I still have myth problems.  Sometimes the cx18 video source works.
Sometimes it doesn't.

Yeah, send it to me off list.  

I'll send to you off list the data I have for various test runs (574 KB
tar.bz2 archive).  The data proves that setting "auto chroma subcarrier
lock speed" helps the cx18/HVR-1600.  The data also shows that the
ivtv/pvr-150 rarely has a "long delay" event compared to the
cx18/HVR-1600(74041).
