Thanks for the link! I found a few things:<br>
<br>
1.) I was, in fact, changing the channel on my cable box (serial cable
was going from my mthtv box to the Motorola STB- I just didn't see the
numbers changing). This seems to be all set.<br>
<br>
2.) Regardless, I don't seem to be getting any cable coming into the
PVR-250. I'm beginning to wonder if perhaps the hardware is screwed,
since I only seem to get channel 4, and changing the channel, while
effective on the cable box, does not show any change in channel in
MythTV. Also, I seem to be getting nothing but white noise unless the
coax cable is jiggled out some.<br>
<br>
Could this be an ivtv thing, not interpreting the cable signal correctly? Or is it more likely to be hardware-related?<br>
<br>
3.) I put the .asoundrc in the mythtv home directory, and when I logged
back in to see if it worked, it froze my X session. It didn't go
through the rest of the startup, and I had to kill my X session. Is
there any way to see why this happened?<br>
<br>
Thanks so much for your help so far, guys!<br>
