Hi Larry,

In the last two patches at this GIT repository:

http://git.linuxtv.org/awalls/v4l-dvb.git?a=shortlog;h=refs/heads/cx18tuner

and, identically, in the last two patches at this Mercurial repository
(if you don't like GIT):

http://linuxtv.org/hg/~awalls/ivtv-cx18/

I have added

- a defintion for the Philips FQ1236 MK5 tuner, and
- an entry in tveeprom mapping index 168 to that new tuner definition 
	with the tuner name set to "TCL M30WTP-4N-E".

Assuming you don't have an XCeive tuner chip, can you test these
patches?  


Regards,
Andy
