Brandon,

Yes I'm running the cx18 driver with an HVR-1600 on a 64 bit OS.

The first analog capture after a modprobe of the cx18 is usually
terrible and unwatchable due to apparently lost frames or no initial
audio followed by audio and lost frames.  The work around is to stop the
analog capture and restart.

Would you characterize the analog capture quality problems as being only
on weak channels or strong channels as well?

I'm not clear on exactly what versions you mean.  Do you have hg
repository names and change ID's?

Since you have the two particular source trees at hand, could you do a
recursive diff so we can see the changes?  That hopefully will narrow
the search for potential causes.
