Silly question, is this NTSC or ATSC, could it not be working because we
switched to digital on Friday ???

failure...halp?

Folks,

I have a somewhat complex question posted on Ubuntuforums at:

http://ubuntuforums.org/showthread.php?p=7469310

Basically, XawTV won't work, which is a prelude to getting ZoneMinder
working (the latest 1.24.1 compiled from source).

It DID work on my initial new Ubuntu Intrepid install, then failed after
installing some part of ZM and it's massive set of dependencies.

Right now my best guess is it's a permissions thing...I *think* the most
crucial error messages are from what happens when Xawtv fails:

---

I also have the dmesg output for the BT878 chipset startup at the link
above, but it looks normal.

Anybody with clue one why Xawtv is blowing up on me, PLEASE sing out :(.
I'm dyin' here...

Thanks,

Jim
