Really odd,

Have had my mythtv box running for a few months now, nothing extravegant: Gentoo 2.6.16, ivtv 0.6.3.

Didn't make any adjustments, was just watching TV, and suddenly the programming stopped. I tried a few things, and eventually tracked the problem down to nothing coming out of my PVR-150 card.

Doing a `cat /dev/video0` (the correct device, as root), results in nothing. Previously, when setting it up, it would spit pure MPEG-2 (binary) into the terminal...

Tried unloading/reloading the IVTV module. Tried switching to composite inputs, switching channels, etc, everything I do ends up getting a blank file in /dev/video0.

I tried plugging the cable into a TV, worked fine, so there is signal there...

While watching TV over the last day, video got choppier, and a bit glitched.

Anyone heard of anything like this before?

Did my card die?

What does dmesg or syslog tells you when the initalizing has started?

Whoops, left out a key bit of detail =P

Everything looks fine on modprobe....

Relevent dmesg:

max ~ # modprobe ivtv tuner=57
max ~ # dmesg
...

mine is exactly the same...

running ivtv-0.8.0 (doesn't work yet, still trying to)

guess the quickest way is to install windows, with orginal driver? thanx you can exclude that the card is dead...

Well, thats not quite helpful

It was working 100%, and just suddenly, while running, quit, and doesn't output anything through /dev/video

Drivers don't normally break in the middle of running (without locking a box)

Also, this box doesn't have any extra space (or good method) to get windows on there, its running on software RAID5... I'll pull the card out later I guess and drop it in a windows box...

Any other thoughts?
