[mythtv-users] Problem with input changing on a Gateway card

[Bret Wade]

Hi, I'm new to the group. I'll start by saying thanks to everyone who's 
contributed to this project. I've been building my first system over the 
last two weeks using .12 on an Asus Pundit with RH9 and the Gateway OEM 
of the PVR-250 using Jarod's very nice guide. My video source is a Sony 
A-4 DirecTV receiver and I am successfully changing channels via serial 
cable using the sony_dss.pl script at http://tarek.2y.net/myth/. I've 
made some newbie mistakes but have been able to get around them all 
using the docs and this list, but I've seen a strange problem that seems 
to be unique to my setup. By trial and error, I've found that I can 
watch live TV from Tuner0 by setting the following values for inputs:

/usr/lib/ivtv/test_ioctl -p 5  
/usr/lib/ivtv/test_ioctl -v input=1,output=1

I haven't seen any mention of anyone else using these values, so I 
assume it's either a peculiarity of the Gateway card or something about 
my setup. The problem is that when I try to record a program, the input 
parameter gets reset to 4 and and I record static. I'm able to work 
around this by setting the input back to 5 in my channel change script, 
but I'm concerned that this issue might indicate that I've got something 
configured wrong. Can anyone explain why the input is getting reset and 
where the default value of 4 is coming from?

Some more information is that when I run the /bin/dmesg command, I see 
"Found an unknown chip, treating it like an iTVC15" instead of the 
expected, "Found an iTVC16 based chip". I have /etc/modules.conf set 
according to Jarod's guide but I've also tried "options tuner type=8" 
which I found mentioned by another Gateway card user. The behavior 
didn't change except that the default became  1 instead of 4.

Thanks,
Bret Wade
