No I didn't. Is this in the mythtv setup or elsewhere? The thing that
seems odd is everytime the channel changes the capture volume goes down
on the hdtv card.

When I mute the line-in I get no sound at all, well on the machine
hooked up to the TV (running the backend), but I get sound if I run
mythtv from my laptop.
However, if I change the channel from the laptop, it brings the capture
volume down still on the hdtv card, and I have to ssh in and bring it
back up to be able to hear the sound.
The main goal is get the machine running the backend to be hooked up to
the TV, and if I'm in a different room to be able to watch TV from my
laptop or a different computer.
I also tried recording, instead of watching it live, and ran into more
issues. I can setup a recording schedule, but the recordings don't make
it to the upcoming recordings. I've tried scheduling from a frontend on
my laptop, the frontend on the backend machine, and mythweb, all with
the same result.
Thankyou for any help!
