[mythtv-users] Dual PVR250 troubleshooting help

[William Powers]

Here's a working modules.conf for comparison purposes:

---------------------------------------------------------
# Video
alias char-major-81	videodev
alias char-major-81-0	ivtv
alias char-major-81-1	ivtv

# IVTV Options
options ivtv ivtv_debug=1 yuv_buffers=60 mpg_buffers=50
options tuner type=2
options msp3400 once=1 simple=1
add below ivtv msp3400 saa7115 tuner
---------------------------------------------------------

Also check in mythconfig and make sure the inputs are connected to the 
proper devices.  I once had both inputs connected to /dev/video0 with 
unpleasant results.

Lastly, here's my /var/log/messages output for comparison purposes; 
maybe it will give you a hint.
