Re: cxm WinTV PVR-150 driver status update

[Vincent Stemen <vince.dragonfly@xxxxxxxxxxx>]

The new cxmo patch provided by Sascha Wildner is working with one of our
pvr-150 cards (the one without FM tuner).  Svideo, composite, and tuner
all tested and working.

OK, Sascha, you are right as I thought.  The second card does not work
since it does not recognize the tuner that has the FM tuner built in.
pciconf shows identical info for both cards.  Hauppage is apparently to
stupid to use a different model number for cards that have a completely
different tuner.

The tuner is identified via iic so pciconf does not show it.  The drive
probably should be fixed to not abort, but to go ahead and initialize
the device even if it cannot identify the tuner, since I see no reason
for the svideo and composite inputs not to still work.

For tuning:
Chet found a very simple utility called setchannel from
http://www.mavetju.org/mail/view_message.php?list=freebsd-multimedia&id=1811146

It worked after a simple fix to an included header path.  But currently
only supports one card with the device hard coded.  Would be easy to
fix.  It seems to be in the public domain.  No copyright info.  It has
the ability to select the input and change channels.

He also found a more sophisticated one from a FreeBSD site

It is a lot more feature rich with the ability to set such things as the
encoding geometry/resolution, etc.  And has the ability to work with
multiple cards.  However, it doesn't work.  It crashes the kernel.  BAD!
BAD!  I would say that is a bug in the driver that needs to be fixed.
But thats probably not that important right now.  We could get to that
later.

I think the more sophisticated *setchannel* utility he found may be the
same one you were talking about porting.  So we will not do any more
with that until you have a chance to look at it.
