Yeah, I was playing with that tool earlier on... When I type in that  
particular command I get this:

# pvr250-setchannel -a on -t -m 2 205.250
ioctl( tfd, METEORSINPUT ) failed.: Invalid argument


The -t flag is causing this particular error message... I can remove  
it and this particular error message will go away, but I realize this  
doesn't help since we want to send the signal to the tuner.

I do not have an IR Blaster setup, my computer is only setup to  
"listen in" on my main satellite feed. This has been working prior  
using the other driver, just FYI.

/var/log/messages reports:

Feb 27 18:21:47 mymachine kernel: could not config dec
Feb 27 18:21:47 mymachine kernel: could not start encoder
Feb 27 18:22:31 mymachine kernel: cxm0: video decoder failed to lock
Feb 27 18:22:32 mymachine kernel: cxm0: audio decoder failed to lock


I'll check on my physical connections in just a few minutes...
