I am running R5A30.1 with a pvr-500. i got everything setup and working with one small problem, i cannot change inputs in mythtv. i know the button to push is 'c' to change inputs and 'y' to change capture devices. currently both capture devices default to tuner 0 and recieve broadcast through the cable input. i have verfied that the s-video input works by using

cat /dev/video1 > test.mpg

i can get mythtv to use the s-video if i go to a command line and enter the command

ivtvctl -d /dev/video1 -p 1

which switches it to the second or aux s-video input. mythtv will then use and display the s-video input. at that point if I press 'c' it will change to the tuner. if I press 'c' again it will not change back to the s-video input.

I have setup the s-video input in mythtv-setup but I just cannot figure out why it will not switch from s-video to tuner and back. is there a config file or a setting that anyone can recommend?
