[pvrusb2] Re: Possible tuner problem with WinTV PVR USB2

[Mike Isely]

Ralph:

You have *excellent* timing.  I just hit this precise problem myself just 
24 hours ago!  The problem is that your device has a new type of tuner in 
it and the support modules don't know how to handle it.  I just got a 
second PVR USB2 device here and tried it for the first time last night - 
and hit exactly the same problem.

So while there's nothing I can do to solve this for you right now, stayed 
tuned (pun intended) because I'm already working this issue.  It will 
probably be a few more days before I have a viable solution (other issues 
outside of this driver are taking my time at the moment), but I'll let you 
know.

For others on the list here - the problem Ralph has encountered here is 
that his device has a "TCL MFNM05-4" tuner inside of it.  This is the 
"metal can" part of the device, and is what downconverts the RF into a 
signal that can be used by other circuits in the box.  This type of tuner 
is apparently very new - as far as I can tell we're blazing a trail here. 
But I have some good traction on this and thanks to some info I've already 
gotten from others I think it won't be long before this is working.
