error
I'm at my wits' end, almost. I've followed every word of Jarod's
instructions to the letter, and I just don't have enough knowledge about
the situation to have any freakin' clue in the matter.
Jarod says:
> # cat /dev/video0 > /tmp/test_capture.mpg (ctrl-c to stop capture)
and my machine says:
> [root at otnemem root]# cat /dev/video0 > /tmp/test_capture.mpg
> cat: /dev/video0: Input/output error
No problem, Jarod says:
> If you get the following error:
> cat: /dev/video0: Input/output error
>
> Run the following commands to reload the driver (this won't work for
PVR-350 users if the ivtv-fb module is loaded -- see above):
> # /sbin/rmmod ivtv
> # /sbin/modprobe ivtv
>
> Now try the capture again.
Yet, my machine says:
> [root at otnemem root]# /sbin/rmmod ivtv
> [root at otnemem root]# /sbin/modprobe ivtv [root at otnemem root]# cat
> /dev/video0 > /tmp/test_capture.mpg
> cat: /dev/video0: Input/output error
All this stuff is entirely new, purchased after my KT133-based system
seemed to suffer from typical DMA problems and I replaced that
overpriced 'silent' (ha!) Overture case and most of the stuff in it.
The OS install is new and clean. I'll post like a million config file
details if you want, but I've done it before today's 100%
paint-by-numbers install.
I think I need some encouragement to even continue to try, actually, as
I'm nearly in a state of mind that would result in my shiny new ME6000
unit being reduced into a pile of very small bits and lit on fire,
around which I'll be dancing like a navajo. Judging by the traffic on
this list, there must be a million people on it. There's gotta be one
guy who's successfully set up FC1 Myth on an ME6000 and a PVR350, one
guy who knows maybe what the hell I'm doing wrong.
Anyone spare a clue? Whaddaya wanna know first? Please CC any replies
to me as well. Hell, call me collect if you want. I don't want to miss
my salvation in this flood, and I'm thinking the apparent FAQness of my
question will only induce the square root of one reply.
- bish
16 Storeys = 1/2 * 9.8 * t^2 , regardless as to weight of MythTV unit.

Just a few initial thoughts:
If I'm not mistaken the ME6000 has an integrated video-out, you might be
at video1 for ivtv.
Check to make sure that /dev/video0 or video1 even exist (did you run
the mknod commands?)
Check lspci -v to make sure the card is even recognized
Check dmesg |grep ivtv to see if ivtv is actually loading.
Worth a shot anyway...
