[mythtv-users] Cannot change frequencies with test_ioctl

[Scott Seaman]

Hey all....


   I am trying to get my Hauppauge WinTV PVR-250 working on my Shuttle 
SB61G2 system.  I have built and installed ivtv using the latest drivers 
from the Hauppauge site, and loaded the various modules per the instructions 
on the IVTV homepage.  I am able to cat video from /dev/video0 into a mpg 
file.  My problem is occurring when I try to change the frequency (aka the 
tv channel) on the card using test_ioctl.

   I first use test_ioctl to set the tuner to tuner 4.  Then, I use 
test_ioctl to try to change the frequency on tuner 4 to 204000 (channel 12 
for cable-hrc).  When I do so, it returns the following message:

>test_ioctl -r tuner=4,freq=204000
>ioctl: VIDIOC_S_FREQUENCY failed

   When I cat /dev/video0, I can get static from tuner 4, so it seems that I 
can at least grab video from the card..  When i switch to different tuners, 
I get the black screen.  I have loaded ivtv.o with the debug flag turned on, 
but I do not receive any verbose error messages.

   Has anyone else had this occur?  It seems strange that everything except 
changing channels should work fine.


My thanks....



Scott
