Kirk-

I didnt see that "[linux-dvb] AverTVHD/NXT2004 patches" thread when it 
was first posted.  Thank you for pointing it out.  I cc'd this email to 
the list, maybe Patrick or Jean-Francois can say something about the 
status of the nxt200x module?

I haven't yet tried Jean-Francois 's patch.... I think I'll give it a 
whirl later on.

About the Philips TUV1236D, Google found this excel sheet that shows 
that it uses NXT2003.  Is the sheet wrong?  ...or maybe some registers 
might be different?  (just a guess)

AVerTVHD also has the NXT2004 inside the the same package with the 
tuner.  It is a TDHU2-008A.  I found some specs for this at:
