[mythtv-users] Channel Changing issue

Hello,

I've been working on getting a MythTv box set up on a RH9 system, using
Jarod's guide.  I have 2 Hauppage PVR-350 cards, both of which I've been
able to get image from using cat /dev/video0(1) > /tmp/test_capture.mpg. 
I can get the default channel when I run mythfrontend, but I am unable to
change channels.  All it does is hesitate, then continue to play the
default channel.  I am able to change the default using ptune.pl, but
that's it. I've rechecked myself numerous times based on the mailinglist
here, the mythtv instructions, and Jarod's guide.  Any help in getting the
channel change issue resolved would be appreciated
